This book was released on 2013-03-08 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection conta ins the results of a number of investiga tions which have been carried out in the Hydrothermal Synthesis Laboratory of the Institute of Crystallography, Academy of Sciences of the USSR; it constitutes a continuation of an earlier collection which appeared in 1968: Hydrothermal Synthesis of Crystals. Problems associated with the synthesis of oxides, simple and complex sulfides, carbonates, silicates, and germanates are consid ered, and a great deal of factual material relating to the growth of single crystals of some of these compounds on a seed is presented. Some of the articles pay special attention to the kinetic asp ect of the growth of crystals; the conditions of growth are relat ed to the morphological characteristics of the growing faces, and the relationship between the habit of the crystals and the oomposi tion and constitution of the solutions is considered. A fair number of articles are concerned with the crystalliza tion of new compounds, most of which have now been synthesized under hydrothermal conditions for the very first time; these in clude ternary chalcohalides of composition AVBvIVVII. zirconates, lithium silicates, and germanates. The collection also contains a description of the apparatus used for precision measurements at high temperatures and pres sures. We hope that this publication will present a better idea of the special characteristics of the hydrothermal method of synthes izing and .growing crystals, and will prove useful to all those in terested in this field of knowledge.

This book was released on 2012-12-06 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Springer-Verlag, Berlin Heidelberg, in conjunction with Springer-Verlag New York, is pleased to announce a new series: CRYSTALS Growth, Properties, and Applications The series will present critical reviews of recent developments in the field of crystal growth, properties, and applications. A substantial portion of the new series will be devoted to the theory, mechanisms, and techniques of crystal growth. Occasionally, clear, concise, complete, and tested instructions fqr growing crystals will be published, particularly in the case of methods and procedures that promise to have general applicability. Responding· to the ever-increasing need for crystal substances in research and industry, appropriate space will be devoted to methods of crystal characterization and analysis in the broadest sense, even though reproducible results may be expected only when structures, microstructures, and composition are really known. Relations among procedures, properties, and the morphology of crystals will also be treated with reference to specific aspects of their practical application. In this way, the series will bridge the gaps between the needs of research and industry, the pos sibilities and limitations of crystal growth, and the properties of crystals. Reports on the broad spectrum of new applications - in electronics, laser tech nology, and nonlinear optics, to name only a few - will be of interest not only to industry and technology, but to wider areas of applied physics as well and to solid state physics in particular. In response to the growing interest in and importance of organic crystals and polymers, they will also be treated.

Available in PDF, EPUB and Kindle. Book excerpt: The structure solution of the new polyoxovanadate compound ([V16O31(OH)7]Cl.15H2O), has been done by the SHELX crystal solution software. The compound was synthesized solvothermally at 170 C in the Northwestern University.The compound crystallizes in the space group C2/c of the monoclinic system with eight formula units in a cell of dimensions a = 18.070 (2) A, b = 17.414 (2) A, c = 15.1154 (18) A, .= 97.696 (2), V= 4713.8 (10) A3 (T = 153 K). The structure is composed of vanadium-oxygen clusters encapsulating Cl anion. Each of the V centers has square pyramidal geometry coordinated by five O atoms. The 16 (VO5) units are fused together through common edges to form (V16O38) cage with Cl anion in the middle.The single crystals of the [Ni(en)3(VO3)2] compound was synthesized by hydrothermal method. [Ni(en)3(VO3)2] compound is in the crystal system of hexagonal and in the space group P61. The unit cell parameters are a = 8.9940 (13) A, b = 8.9940 (13) A, c = 34.001 (7) A and alpha = 90 , B = 90 , y = 120 . The structure is composed of VO4 tetrahedras which are joined with others by sharing corners into infinite chains running along the c axis. The complex cation [Ni(en)3]2+ are located between the chains The chain in the compound has a repetitive sequence of 12-nuclear corner-sharing tetrahedras. The compound was synthesized at 160 C for 3 days in the steel reaction autoclaves which have PTFE (Polytetrafluoroethylene) cups in them.By the reaction of the reactants NH4VO3, Ni(NO3)2.6H2O, H3BO3 with H2O the orange crystals of NH4(V3O8) and the green unknown crystals were obtained at 160 C in 3 days..By the reaction of the reactants NaVO3, Ni(NO3)2.6H2O, H3BO3, NH2CH2CH2NH2, with the solvents H3PO4 and H2O the green bulk unknown crystals were obtained at 160 C in 3 days.the reaction of the reactants B4K2O7.H2O, KVO3 with H2O and NH2CH2CH2NH2 brown unknown crystals were obtained at 170 C in 5 days.We have also done some crystal growth studies in our laboratory. There are several known compounds as CoV2O6(H2O)2, Co(VO)2(PO4)2(H2O)4, which were also synthesized in our laboratory with good yields. These crystals were synthesized with other methods and characterized. However we were able to grow their crystals in good shape and size by using hydrothermal method. CoV2O6(H2O)2 was obtained from the reaction of NH4VO3, Co(NO3)2.6H2O and H3BO3. The compound crystallizes in the space group Pnma (62) of the orthorhombic system in a cell of dimensions, a = 5.572 A,b = 10.70 A, c = 11.860 A, alpha = Beta = y = 90 , V = 707.69 A3. CoV2O6(H2O)2 was prepared in a steel autoclave by using ultra pure water as the solvent and heated at 160 C for 3 days. Red prism shaped crystals of the reported materials were obtained with the orange plates in a red-orange crystalline powder.

Download or read book Crystal Growth Technology written by K. Byrappa and published by Springer Science & Business Media. This book was released on 2003-04-17 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crystals are the unacknowledged pillars of modern technology. The modern technological developments depend greatly on the availability of suitable single crystals, whether it is for lasers, semiconductors, magnetic devices, optical devices, superconductors, telecommunication, etc. In spite of great technological advancements in the recent years, we are still in the early stage with respect to the growth of several important crystals such as diamond, silicon carbide, PZT, gallium nitride, and so on. Unless the science of growing these crystals is understood precisely, it is impossible to grow them as large single crystals to be applied in modern industry. This book deals with almost all the modern crystal growth techniques that have been adopted, including appropriate case studies. Since there has been no other book published to cover the subject after the Handbook of Crystal Growth, Eds. DTJ Hurle, published during 1993-1995, this book will fill the existing gap for its readers. The book begins with "Growth Histories of Mineral Crystals" by the most senior expert in this field, Professor Ichiro Sunagawa. The next chapter reviews recent developments in the theory of crystal growth, which is equally important before moving on to actual techniques. After the first two fundamental chapters, the book covers other topics like the recent progress in quartz growth, diamond growth, silicon carbide single crystals, PZT crystals, nonlinear optical crystals, solid state laser crystals, gemstones, high melting oxides like lithium niobates, hydroxyapatite, GaAs by molecular beam epitaxy, superconducting crystals, morphology control, and more. For the first time, the crystal growth modeling has been discussed in detail with reference to PZT and SiC crystals.

Available in PDF, EPUB and Kindle. Book excerpt: The present volume continues the tradition of the preceding volumes. covering a wide range of crystal growth problems and treating aspects of critical importance for crystalliza tion. Changes in this field of knowledge have. however, changed the criteria for selection of papers for inclusion in this series. The increasing role of crystals in science and technology is even more apparent today. The study and utilization of these highly perfect objects of nature considerably facilitates progress in the physics and chemistry of solids. quantum electronics, optics, microelectron ics, and other sciences. The demand for crystals and crystal devices has grown steadily and has led to the emergence and rapid growth of the single crystal industry (we can safely saythat the state ofthe art in this industry is indicative ofthe overall scientific and technolo- cal potential of a country). At the same time, the introduction of crystallization techniques into other industries is gaining ever-increasing importance. To illustrate this last state ment, we can mention the fabrication of textured structural materials and direct methods of metal reduction in ores by using chemical vapor transport techniques. Crystallization tech ll niques progress both in "width" and in "depth : traditional methods are modernized. and novel techniques appear, some of them at the junction of the already existing technologies (for example, flux growth of crystals, growth from vapor with participation of the liquid phase, etc. ).

Download or read book Aqueous Systems at Elevated Temperatures and Pressures written by Roberto Fernandez-Prini and published by Elsevier. This book was released on 2004-07-06 with total page 767 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Association for the Properties of Water and Steam (IAPWS) has produced this book in order to provide an accessible, up-to-date overview of important aspects of the physical chemistry of aqueous systems at high temperatures and pressures. These systems are central to many areas of scientific study and industrial application, including electric power generation, industrial steam systems, hydrothermal processing of materials, geochemistry, and environmental applications. The authors’ goal is to present the material at a level that serves both the graduate student seeking to learn the state of the art, and also the industrial engineer or chemist seeking to develop additional expertise or to find the data needed to solve a specific problem. The wide range of people for whom this topic is important provides a challenge. Advanced work in this area is distributed among physical chemists, chemical engineers, geochemists, and other specialists, who may not be aware of parallel work by those outside their own specialty. The particular aspects of high-temperature aqueous physical chemistry of interest to one industry may be irrelevant to another; yet another industry might need the same basic information but in a very different form. To serve all these constituencies, the book includes several chapters that cover the foundational thermophysical properties (such as gas solubility, phase behavior, thermodynamic properties of solutes, and transport properties) that are of interest across numerous applications. The presentation of these topics is intended to be accessible to readers from a variety of backgrounds. Other chapters address fundamental areas of more specialized interest, such as critical phenomena and molecular-level solution structure. Several chapters are more application-oriented, addressing areas such as power-cycle chemistry and hydrothermal synthesis. As befits the variety of interests addressed, some chapters provide more theoretical guidance while others, such as those on acid/base equilibria and the solubilities of metal oxides and hydroxides, emphasize experimental techniques and data analysis. - Covers both the theory and applications of all Hydrothermal solutions - Provides an accessible, up-to-date overview of important aspects of the physical chemistry of aqueous systems at high temperatures and pressures - The presentation of the book is understandable to readers from a variety of backgrounds

Available in PDF, EPUB and Kindle. Book excerpt: There is no question that the field of solid state electronics, which essentially began with work at Bell laboratories just after World War II, has had a profound impact on today's Society. What is not nearly so widely known is that advances in the art and science of crystal growth underpin this technology. Single crystals, once valued only for their beauty, are now found, in one form or another in most electronic, optoelectronic and numerous optical devices. These devices, in turn, have permeated almost every home and village throughout the world. In fact it is hard to imagine what our electronics industry, much less our entire civilization, would have been like if crystal growth scientists and engineers were unable to produce the large, defect free crystals required by device designers. This book brings together two sets of related articles describing advances made in crystal growth science and technology since World War II. One set is from the proceedings of a Symposium held in August 2002 to celebrate 50 years of progress in the field of crystal growth. The second contains articles previously published in the newsletter of the American Association for Crystal Growth in a series called "Milestones in Crystal Growth".The first section of this book contains several articles which describe some of the early history of crystal growth prior to the electronics revolution, and upon which modern crystal growth science and technology is based. This is followed by a special article by Prof. Sunagawa which provides some insight into how the successful Japanese crystal growth industry developed. The next section deals with crystal growth fundamentals including concepts of solute distribution, interface kinetics, constitutional supercooling, morphological stability and the growth of dendrites. The following section describes the growth of crystals from melts and solutions, while the final part involves thin film growth by MBE and OMVPE.These articles were written by some of the most famous theorists and crystal growers working in the field. They will provide future research workers with valuable insight into how these pioneering discoveries were made, and show how their own research and future devices will be based upon these developments. · Articles written by some of the most famous theorists and crystal growers working in the field· Valuable insight into how pioneering discoveries were made.· Show how their own research and future devices will be based upon these developments

Book excerpt: Papers from the Sixth All-Union Conference on Growth of Crystals comprise Volume 16 of this series. The articles were chosen with a view to more fully elucidate the basic problems of crystal growth as reflected in domestic and foreign reviews and in original studies. This volume consists of six parts. Part I is devoted to mechanisms of crystal growth that are important for production of materials with given properties. This part examines the temporal evolution of an inhomogeneous state and the array of semicellular and eutectic structures during microstructure formation, the effect of impurity on the nonequi librium vacancy concentration in a growing crystal, and the role of soluble and insoluble impurities in the birth and growth of crystals. Part II deals with the synthesis and electrophysical properties of novel solid electrolytes that are promis ing for practical use, analysis and correlation of the large amount of data on growth by the Bridgman-Stockbar ger method of single crystals of fluorite phases far from stoichiometry, and the hydrothermal chemistry and growth of hexagonal germanium dioxide.
