Download or read book W Tungsten written by and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present supplement volume, A 7, is the first of a triad, A 5 to A 7, dealing with the chemical reactions of metallic tungsten. It describes the reactions with inorganic and organic compounds, except for formation reactions of organotungsten compounds. Volume A 6, to appear at the beginning of 1988, will cover the reactions of tungsten with metallic elements. Volume A 5, in preparation for 1988/89, will contain the reactions with nonmetallic elements and, in addition, cover the electrochemistry of tungsten. With the appearance of this last volume, the present knowledge of the chemistry of tungsten will be compiled in more than 1000 pages. In the Gmelin main volume on tungsten, published in 1933, the presentation of the information then available on the same subject required less than 6 pages. This enormous increase in relevant data over the last fifty years is stupefying, considering the fact that tungsten is a rather inert metal which is resistant to most chemical agents up to high temperatures.With afew exceptions,in fact, it was not so much the reactions of bulk tungsten which attracted the interest of the experimenters as the reactions taking place at its surface. This comes about for practical as well as scientific reasons.

Available in PDF, EPUB and Kindle. Book excerpt: The volume describes physical properties of tungsten metal and covers specifically surface properties, electron emission, and field evaporation. Tungsten surfaces are probably the most extensively studied metal surfaces. Recently, experimentalists and theorists have focussed their interest on the atomic structure, lattice dynamics, and electronic properties of the W(100) surface. While the structure of the reconstructed low-temperature surface is well established, there are still unresolved problems concerning the structure at and above room temperature, the nature of the phase transition, and the driving force for the reconstruction. There are numerous and partly conflicting data on the surface energy, the self-diffusion parameters, and the work function of single-crystal and polycrystal tungsten surfaces. Electron emission, which is of fundamental importance for many applications, comprises thermionic, field, photofield, and photoelectric emission as well as emission induced by impinging electrons, atoms, or ions. Pioneering work in areas like thermionic or field emission is comprehensively discussed. Very recent studies of valence-band and core-level spectra moreover provide detailed information on intrinsic surface properties.

Download or read book Metal Chemical Reactions with Metals Antimony to Barium written by Ernst Koch and published by Springer. This book was released on 1991-09-15 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present volume completes the description of the interactions and chemical reactions of elemental tungsten with metallic elements, treating its reactions with antimony, bismuth, and the alkali and alkaline earth metals. The reactions of tungsten with these elements are in most cases confined to surface regions. Corrosion of tungsten and mutual solubility are usually very low. An exception is the W - Be system, in which several intermetallic phases are formed. The surface processes in some of the other systems covered in the present volume evoked considerable scientific and practical interest, documented by the large number of publications. This holds particularly for the Cs-on-W and Ba-on-W surface systems. Cs- and Ba-activated tungsten electrodes were and are used in many technical and laboratory appliances. One example is the Cs diode device for thermionic energy conversion. Surface ionization of Cs and W is widely applied in ion sources and for some time attracted great attention with respect to its potential use in ion rocket propulsion engines. Cs-on-W is also a logical system for basic research on chemisorption due to the propitious chemical, crystallographic, and atomic properties of adsorbent and adsorbate. The majority of existing models for the chemisorption bond has been experimentally checked on this system. The particular interest in the W - Cs and W - Ba systems is reflected in the large portion of the text (256 pages) devoted to these systems.

This book was released on 2007-12-31 with total page 4059 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chemistry of the Actinide and Transactinide Elements is a contemporary and definitive compilation of chemical properties of all of the actinide elements, especially of the technologically important elements uranium and plutonium, as well as the transactinide elements. In addition to the comprehensive treatment of the chemical properties of each element, ion, and compound from atomic number 89 (actinium) through to 109 (meitnerium), this multi-volume work has specialized and definitive chapters on electronic theory, optical and laser fluorescence spectroscopy, X-ray absorption spectroscopy, organoactinide chemistry, thermodynamics, magnetic properties, the metals, coordination chemistry, separations, and trace analysis. Several chapters deal with environmental science, safe handling, and biological interactions of the actinide elements. The Editors invited teams of authors, who are active practitioners and recognized experts in their specialty, to write each chapter and have endeavoured to provide a balanced and insightful treatment of these fascinating elements at the frontier of the periodic table. Because the field has expanded with new spectroscopic techniques and environmental focus, the work encompasses five volumes, each of which groups chapters on related topics. All chapters represent the current state of research in the chemistry of these elements and related fields.

Download or read book Tungsten written by Erik Lassner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why does someone write a book about Tungsten? There are several reasons and precedents for this, the most important of which is that the last book on tungsten was written more than 20 years ago, in 1977, by St. W H. Yih and Ch T. Wang. During the intervening period there have been many new scientific and technological developments and innova tions, so it was not only our opinion but the view of many other members of the "tungsten family" that it was time to start writing a new book about tungsten. Preparations of the new book began in 1994. further impetus to the project was provided by the realization that in spite of this new knowledge having been presented at seminars or published in the technical press, a general acknowledgement of it by the majority of technicians and scientists is still far from being realized. It is our hope that this book will significantly contribute to a broader acceptance of recent scientific and technological innovations. An important prerequisite for such a project is the availability of a recently retired, experienced person willing to devote his time and talents to the tedious part of the exercise.
