Available in PDF, EPUB and Kindle. Book excerpt: Doped by isovalent or heterovalent foreign impurities (F), II–VI semiconductor compounds enable control of optical and electronic properties, making them ideal in detectors, solar cells, and other precise device applications. For the reproducible manufacturing of the doped materials with predicted and desired properties, manufacturing technologists need knowledge of appropriate ternary system phase diagrams. A guide for technologists and researchers at industrial and national laboratories, Ternary Alloys Based on II-VI Semiconductor Compounds collects all available data on ternary II–VI–F semiconductor materials. It presents ternary phase diagrams for the systems and includes data about phase equilibriums on the cross sections. The book is also suitable for phase diagram researchers, inorganic chemists, and solid state physicists as well as students in materials science, engineering, physical chemistry, and physics. The authors classify all materials according to the periodic groups of their constituent atoms (i.e., possible combinations of Zn, Cd, and Hg with chalcogens S, Se, and Te) and additional components in the order of their group number. Each ternary system database description contains the diagram type, possible phase transformation and physical–chemical interaction of the components, equilibrium investigation methods, thermodynamic characteristics, and the sample preparation method. In some cases, the book illustrates the solid and liquid-phase equilibriums with vapor because of their importance to crystal growth using the vapor–liquid–solid technique. It also presents data on the homogeneity range as well as baric and temperature dependences of solubility impurities in the semiconductor lattice and the liquid phase.

Available in PDF, EPUB and Kindle. Book excerpt: The feldspars form the most abundant group of minerals in the crust of the Earth and Moon and also occur in many meteo rites. They playa fundamental role in all rock-forming processes at shallow depths, but are rare or absent from the upper mantle. Their detailed study is thus essential for the understan ding of such varied processes as magma genesis and differentia tion, metamorphism, al teration, erosion and sedimentation. This interest is show by the fact that two previous NATO Advanced Study Institutes on feldspars were held in Oslo in 1962 and in Manchester in 1972. The feldspars are particularly sui table for detailed studies, as they have very simple chemistry and develop some of the most complex microstructures known. The microstructures are often slow to form but are easily preserved, so that they are potentially extremely informative about the geological history of the rocks in which they occur. Furthermore, their study involves physical and chemical methods of increasing sophistication so that the results obtained are not always immediately understandable to research workers outside the field of modern mineralogy. Progress in knowledge about feldspars is probably slower in penetrating the fields of petrology and geochemistry than that on other mineral groups. For these reasons among others, i~ was particularly appropriate to hold a third NATO ASI on feldspars approximately ten years after the last one.

Available in PDF, EPUB and Kindle. Book excerpt: Feldspar minerals make up 60% of the crust of the Earth. They are stable in the upper mantle, and are so abundant in the crust that they form the basis of the classification of igneous rocks. At the surface, feldspars weather to form clay minerals which are the most important mineral constituent of soils. The articles in this book review the chemical reactions of feldspars over the whole sweep of pressure and temperature regimes in the outer Earth, and describe the fundamental aspects of crystal structure which underlie their properties. The book covers intracrystalline reactions, such as order-disorder transformations and exsolution, and transfer of stable and radiogenic isotopes, which can be interpreted to provide insights into the thermal history of rocks. It is suitable for final year undergraduates or research workers.

Available in PDF, EPUB and Kindle. Book excerpt: Hans Ramberg is working in an area of geology where 60 years are a short, often negligible period of time. This is not so in the lives of men. For us it is a time for evaluating past accomplishments and a time for friends to express their appreciation and admiration. Some universities have become famous for this ability to foster eminent scientists in one or several fields. The success of Cambridge University in physics is a well-known example, but if we ask ourselves whether the success of Oslo University in earth sciences is not equally astonishing, then we see that Hans is yet another example of this process; but it is not the whole story. There were certainly promising prospects when he started his studies in geology: V. M. Goldschmidt had just come back from G6ttingen in Germany and Tom Barth had returned from the Geophysical Laboratory in Washington, D.C. Two leaders in geochemistry and petrology at the same time! Hans became a student of Barth, specializing in metamorphic rocks and their problems; but soon the situation changed. Norway was occupied by the Germans and the possibili ties for university studies almost vanished. However, in spite of all difficulties he obtained his Ph.D. in 1946 and began participating in the geological mapping of Greenland. In 1947 he went to the University of Chicago and stayed there until 1961 when he came to his present position in the University of Uppsala, Sweden.

Available in PDF, EPUB and Kindle. Book excerpt: This exhaustive work in three volumes with featuring cross-reference system provides a thorough overview of ultra-high temperature materials – from elements and chemical compounds to alloys and composites. Topics included are physical (crystallographic, thermodynamic, thermo-physical, electrical, optical, physico-mechanical, nuclear) and chemical (solid-state diffusion, interaction with chemical elements and compounds, interaction with gases, vapours and aqueous solutions) properties of the individual physico-chemical phases and multi-phase materials with melting (or sublimation) points over or about 2500 °C. The first volume focuses on carbon (graphite/graphene) and refractory metals (W, Re, Os, Ta, Mo, Nb, Ir). The second and third volumes are dedicated solely to refractory (ceramic) compounds (oxides, nitrides, carbides, borides, silicides) and to the complex materials – refractory alloys, carbon and ceramic composites, respectively. It will be of interest to researchers, engineers, postgraduate, graduate and undergraduate students in various disciplines alike. The reader is provided with the full qualitative and quantitative assessment for the materials, which could be applied in various engineering devices and environmental conditions at ultra-high temperatures, on the basis of the latest updates in the field of physics, chemistry, materials science, nanotechnology and engineering.

Available in PDF, EPUB and Kindle. Book excerpt: This second volume carries on the excellent work of its predecessor, ex tending its scope to other melts and to other techniques. It continues to present first-hand understanding and experience of this difficult and demanding field. There is ever present the trade-off or reconciliation between the novel chemistry of systems not dominated by the mediating influence of a supposedly indifferent solvent and the high temperatures required to effect the fluidity of the system. At the limit, the very high temperatures so increase the rates of all reactions as to dissolve the temporal difference between the thermodynamic and the kinetic view of chemistry. What can happen will happen and invariably does happen. Vessels corrode, the apparatus becomes a reactant, and the number of tolerant materials able to withstand the attack shrinks to graphite, boron carbide or, if all else fails, to frozen parts of the molten salt itself. It is probably true that there is no limit to man's ingenuity but I believe that God gave us molten salts just to test that thesis. If there is ever a Molten Salt Club, and Englishmen love clubs, its membership will be exclusive. It would certainly include the authors of this series. Graham Hills University of Strathclyde ix Preface In the first volume of this series, we expressed our contention that a real need existed for practical guidance in the field of molten salt experimentation.

Book excerpt: By browsing about 10 000 000 scientific articles of over 200 major journals mainly in a 'cover to cover approach' some 200 000 publications were selected. The extracted data is part of the following fundamental material research fields: crystal structures (S), phase diagrams (also called constitution) (C) and the comprehensive field of intrinsic physical properties (P). This work has been done systematically starting with the literature going back to 1900. The above mentioned research field codes (S, C, P) as well as the chemical systems investigated in each publication were included in the present work. The aim of the Inorganic Substances Bibliography is to provide researchers with a comprehensive compilation of all up to now published scientific publications on inorganic systems in only three handy volumes.

Available in PDF, EPUB and Kindle. Book excerpt: Doped by isovalent or heterovalent foreign impurities, II–VI semiconductor compounds enable control of optical and electronic properties, making them ideal in detectors, solar cells, and other precise device applications. Quaternary alloys allow a simultaneous adjustment of band gap and lattice constant, increasing radiant efficiency at a wide range of wavelengths. Quaternary Alloys Based on II–VI Semiconductors consolidates data pertaining to diagrams of quaternary systems based on these semiconductor compounds. The book illustrates up-to-date experimental and theoretical information about phase relations based on II–VI semiconductor systems with four components. It critically evaluates many industrially significant systems presented in two-dimensional sections for the condensed phases. The author classifies all materials according to the periodic groups of their constituent atoms and additional components in the order of their group number. Each quaternary database description contains brief information on the diagram type, possible phase transformations and physical–chemical interactions of the components, thermodynamic characteristics, and methods for equilibrium investigation and sample preparation. Most of the phase diagrams are in their original form. For those with varying published data, the text includes several versions for comparison. This book provides invaluable data for technologists and researchers involved in developing and manufacturing II–VI semiconductors at industrial and national laboratories. It is also suitable for phase relations researchers, inorganic chemists, and semiconductor physicists as well as graduate students in materials science and engineering.

(1973) measured the distribution of REE at 850 C and 750 bars pressure between a natural plagioclase, An , and gaseous water. The rare earths 65 favored the plagioclase by a factor which varies from about 25 for Ce to 10 for Lu. Data were also obtained for forsterite, diopside, enstatite and two rhyolite glasses, on the one hand, and water on the other hand, thereby permitting estimation of the partition coefficients between all pairs of phases. 14. 4 Chemical Substitution in Natural Feldspars 14. 4. 1 Introduction It is quite impracticable to give all the data on chemical substitution in natural feldspars: indeed many of the details are significant only to some particular pegmatite or rock body. As far as possible, emphasis is placed on features of general interest to crystal chemists and to petrologists. Ironically the well established features can be described more easily than the uncertain ones, and unfortunately it is necessary to use valuable space on data of dubious value. The bibliography is fairly complete, but it was impracticable to locate all data, especially those in obscure journals. Each reference is followed by a list of the elements referred to in the paper, thereby permitting a reader to compile a fairly compre hensive set of references on any chosen element. Not all papers are mentioned in the text. The book on Geochemistry and Mineralogy of Rare Elements, etc.
