This book was released on 2021-11-17 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thesis focuses on the syntheses, structural characterizations and chemical bonding analyses for several ternary R–M–Ge (R = rare earth metal; M = another metal) intermetallics. The challenges in understanding the main interactions governing the chemistry of these compounds, which lead to our inability to predict their formation, structure and properties, are what provided the motivation for this study. In particular, the R2MGe6 (M = Li, Mg, Al, Cu, Zn, Pd, Ag), R4MGe10-x (M = Li, Mg), R2Pd3Ge5, Lu5Pd4Ge8, Lu3Pd4Ge4 and Yb2PdGe3 phases were synthesized and structurally characterized. Much effort was put into the stabilization of metastable phases, employing the innovative metal flux method, and into the accurate structure solution of twinned crystals. Cutting-edge position-space chemical bonding techniques were combined with new methodologies conceived to correctly describe the Ge–M, Ge–La and also La–M polar-covalent interactions for the La2MGe6 (M = Li, Mg, Al, Cu, Zn, Pd, Ag) series. The present results constitute a step forward in our comprehension of ternary germanide chemistry as well as providing a good playground for further investigations.

This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The aspects of composition, structure-bonding, and properties, along with the reasons governing the formation of one phase over another all still, quite surprisingly remain an open question concerning intermetallic compounds. This work was therefore inspired by a need to better understand the above-mentioned characteristics for several binary and ternary rare-earth (RE) germanides. The structure and properties discussed herein, report the crystal chemistry and physical properties associated with over 40 new binary and ternary intermetallic compounds synthesized from their respective elements using either classical solid state reactions or by the metal flux growth technique. All contain the Group 14 element Ge along with several of the lanthanide f-block metals (commonly referred to as rare-earths) which represent the majority of the binary compounds while the ternary compounds include the additional combination of select s - and p -block metals and semi-metals - Mg, Ca, In, Sn. Their crystal structures and compositions were determined using a number of techniques including single-crystal and powder X-ray diffraction, electron diffraction and electron microscopy. Along with the structure and bonding, this dissertation devotes a discussion to the physical properties which are exhibited by these compounds as a function of temperature or magnetic field in association with their bulk magnetic susceptibility, electrical resistivity and heat-capacity. The results from these along with certain similarities in their structure and bonding allows for the classification of five families organized based on their chemical formulae which include the following: (1) RE 5-x Mg x Ge 4 (RE = Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, and Y) containing two types of Ge-Ge dimers of which their bonding can be affected by small changes in the overall composition; (2) RE 2 InGe2 (RE = Sm, Gd, Tb, Dy, Ho, and Yb) containing [Ge 2] dimers connected with four-coordinated In atoms which results in planar InGe 2 layers; (3) RE Sn 1+x Ge1-x (RE = Y, Gd, Tb, Dy, Ho, Er, Tm), RE 2 [Sn x Ge 1-x] 5 (RE = Nd, Sm), RE [Sn x Ge 1-x]2 (RE = Gd, Tb), which uniquely contain two group 14 elements Ge and Sn that are found to preferentially occupy specific crystallographic sites - these being infinite zig-zag chains of Germanium and square sheets of Sn; (4) RE 3 Ge 4 (RE = Gd, Tb, Dy, Ho, Er, Tm, and Y) containing fused fragments of two-bonded zig-zag Germanium atoms; (5) RE 3 Ge 5 (RE = Sm, Gd, Tb, Dy) an example of polymorphism with two dimensional and three dimensional anionic sub-networks with different orientations of zig-zag chains of Germanium.

Available in PDF, EPUB and Kindle. Book excerpt: The growth and development witnessed today in modern science, engineering, and technology owes a heavy debt to the rare, refractory, and reactive metals group, of which niobium is a member. Extractive Metallurgy of Niobium presents a vivid account of the metal through its comprehensive discussions of properties and applications, resources and resource processing, chemical processing and compound preparation, metal extraction, and refining and consolidation. Typical flow sheets adopted in some leading niobium-producing countries for the beneficiation of various niobium sources are presented, and various chemical processes for producing pure forms of niobium intermediates such as chloride, fluoride, and oxide are discussed. The book also explains how to liberate the metal from its intermediates and describes the physico-chemical principles involved. It is an excellent reference for chemical metallurgists, hydrometallurgists, extraction and process metallurgists, and minerals processors. It is also valuable to a wide variety of scientists, engineers, technologists, and students interested in the topic.

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.
