Book excerpt: In recent years there has been a marked increase in the demand for highpurity metals and compounds for use in spectrochemical analysis, one of the principal uses being the preparation of standards in the absence of analyzed samples. High purity in this report generally refers to a purity greater than 99.5 per cent. However, a few metals or compounds with purity less than this figure have been included because no source for the higher purity material was known. The results of the present survey of high-purity materials, shown in Table 62,5 include 86 elements or their compounds and 864 entries. The data have been assembled in tabular form beginning with actinium and continuing in alphabetical order through zirconium. Under each element, the metal is listed first, followed by the compounds, salts, or solutions, which are also alphabetized. Compounds are listed under the element of particular interest; for example, ammonium molybdate is listed under molybdenum, and potassium perrhenate under rhenium. Entries for a particular metal or compound are arranged in the order of decreasing purity as given by the supplier. When the purity of a material was not given by the supplier, the material is listed last. Under the description column of the table, an attempt is made to give all available pertinent information including impurity elements, concentrations, form of material, and supplier's catalog numbers.

This book was released on 1999-09-07 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent developments in microelectronics technologies have created a great demand for interlayer dielectric materials with a very low dielectric constant. They will play a crucial role in the future generation of IC devices (VLSI/UISI and high speed IC packaging). Considerable efforts have been made to develop new low as well as high dielectric constant materials for applications in electronics industries. Besides achieving either low or high dielectric constants, other materials' properties such as good processability, high mechanical strength, high thermal and environmental stability, low thermal expansion, low current leakage, low moisture absorption, corrosion resistant, etc., are of equal importance. Many chemical and physical strategies have been employed to get desired dielectric materials with high performance. This is a rapidly growing field of science--both in novel materials and their applications to future packing technologies. The experimental data on inorganic and organic materials having low or high dielectric constant remail scattered in the literature. It is timely, therfore, to consolidate the current knowledge on low and high dielectric constant materials into a sigle reference source. Handbook of Low and High Dielectric Constant Materials and Their Applications is aimed at bringing together under a sigle cover (in two volumes) all low and high dielectric constant materials currently studied in academic and industrial research covering all spects of inorgani an organic materials from their synthetic chemistry, processing techniques, physics, structure-property relationship to applications in IC devices. This book will summarize the current status of the field covering important scientific developments made over the past decade with contributions from internationally recognized experts from all over the world. Fully cross-referenced, this book has clear, precise, and wide appeal as an essential reference source for all those interested in low and high dielectric constant material.
Download or read book High Purity Refractory and Rare Metals written by Grigorii Grigorevich Deviatykh and published by Cambridge International Science Publishing. This book was released on 1997 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-purity refractory and rare metals are used on an increasing scale in technology and fundamental investigations. The authors examine methods of producing these metals, single-crystal growth, and properties in relation to the content of impurities and perfection of the crystal lattice. Distillation processes are analysed in detail with consideration for their deviations from thermodynamic equilibrium, including special features of evaporation from the open surface. An optimum programme of the variation of the parameters of zone melting resulting in the required degree of purification with the minimum number of passes is determined. New mechanisms of recrystallisation in the solid phase in the presence of the liquid phase are described.
