Available in PDF, EPUB and Kindle. Book excerpt: Reduction of small charges of uranium tetrafluoride with magnesium proved to be successful. By hand-tamping of UF4- Mg blend, tap densities ranging between3.1 and 3.4 g/cc were obtained. The reduction yields for these densities ranged from 72.79 to 93.71%. In the case of machine-compacted UF4-Mg blend having tap densities from 3.58 to 3.68 g/cc, reduction yields were higher, ranging between 91.45 and 97.2%. Machine-compacted blends gave much more uniform temperature distribution curves during the preheating period, as a result of higher tap densities. The best yields were obtained by firing a machine- compacted blend containing 5% Mg excess at a furnace temperature of 650 deg C, giving an average crude metal yield of 96.3%. However, the high carbon content of 174 ppm in the crude uranium biscuits obtained by compacts reduction, as a result of hydrocarbon binder presence, appeared to be a disadvantage. Attempts were also made to demonstrate the initiation of the reduction reaction at temperatures lower than 500 deg C by taking x-ray-diffraction patterns of the samples of the UF4-Mg charges heated up to various temperatures.

Download or read book The Production of Uranium by the Reduction of UF4 by Mg written by and published by . This book was released on 1945 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to difficulties encountered in the production of calcium metal in adequate quantity and of adequate purity at low cost, it became desirable to replace calcium by a cheaper metal in the production of uranium. Because of the heats of formation of its compounds, its relative stability in air, and its cheapness in high purities, magnesium was the best suited metal for the purpose. Since the heat of reaction of the reduction of UF4 by Mg was not sufficient to melt the products, it was necessary to add heat to the system. This was done in experimental studies both by preheating the reactants before reaction was initiated and by the use of a simultaneous auxiliary reaction producing more heat than the primary reaction. For the latter purpose the reductions of KClO3, K2S2O8 and of other salts by Mg were suitable reactions. The use of 'boosters' or auxiliary oxidants involved extra work and materials, thus increasing costs and offering additional opportunity for contamination, hence the preheating of the reactants was adopted for large scale production.

This book was released on 2018-01-08 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: A review of contemporary actinide research that focuses on new advances in experiment and theory, and the interplay between these two realms Experimental and Theoretical Approaches to Actinide Chemistry offers a comprehensive review of the key aspects of actinide research. Written by noted experts in the field, the text includes information on new advances in experiment and theory and reveals the interplay between these two realms. The authors offer a multidisciplinary and multimodal approach to the nature of actinide chemistry, and explore the interplay between multiple experiments and theory, as well as between basic and applied actinide chemistry. The text covers the basic science used in contemporary studies of the actinide systems, from basic synthesis to state-of-the-art spectroscopic and computational techniques. The authors provide contemporary overviews of each topic area presented and describe the current and anticipated experimental approaches for the field, as well as the current and future computational chemistry and materials techniques. In addition, the authors explore the combination of experiment and theory.

This book was released on 1990-12-31 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of the rare earths has entered its third century; trans uranium elements are now a half century old. Both the lanthanide and actinide ele ments, 30 elements altogether, are f elements, meaninj that their metallic 2 1 1 electronic configurations are typically 6s 5d 4f" and 7s 6d 5f" respectively. To an elementary approximation as summarized in the 'average inorganic chemistry textbook, these configurations cause their chemistry to be described by the trivalent state accompanied by less interesting effects such as the lanthanide contraction. However, the discovery of divalent and tetravalent lanthanides and di- to seven-valent actinides hinted at the existence of more interesting although still classic solid-state and coor dination chemistry. Metallic halides and chalcogenides and electron-poor cluster compounds have been the outgrowth of many synthetic efforts during the past 25 years or so. These days, one can say that the lan thanides and actinides are not at all boring; the fascination arises from every element being an individual, having its own chemistry.

Book excerpt: Single crystals of over 100 different electronically active materials have been synthesized using a variety of methods, including growth by flame-fusion, flux, melt, gel diffusion, low-temperature solution, vapor, as well as synthesis by ultra-high-pressure techniques. These crystals, including a large number of doped specimens, emphasize oxides, garnets, silicates, ferrites, fluorides, as well as a large variety of other electromagnetic materials. Charts are presented giving summary data on single crystals grown, percentage and kind of dopants, growth methods and apparatus, crystal dimensions and other physical characteristics, primary research interest or use, crystal system, class, space group, and pertinent references. Several of the growth methods and recent Laboratory accomplishments are described. (Author).
