SECTION I - CLASS DEFINITION. This is the generic class for specialized metallurgical processes for producing or recovering metals from metal compounds, ores, or scrap metal and for refining liquid metal and for compositions used in these specialized metallurgical processes, consolidated metal powder compositions, and loose metal particulate mixtures.
This review examines from the historical standpoint the development of silicon nitride and of its processing into a range of high‐grade ceramic materials. F. Disdier, E. Cierniak and N. Eustathopoulos, The crucible/silicon interface in directional Microstructural connectivity in sintered ex-situ MgB2 bulk superconductors, Journal of
Carbide powders can be partially or completely converted to substantially densely-packed carbon nanotubes by thermochemical treatment. When partially converted, the resulting materials can consist of a metal carbide core, such as silicon carbide, onto which a surface layer of fullerenic carbon, such as carbon nanotubes, has been grown.

2019-3-11 · The preparation of high-purity and -quality gallium nitride nanowires is accomplished by a alytic growth using gallium and ammonium. A series of alysts and different reaction parameters were applied to systematically optimize and control the vapor−liquid−solid (VLS) growth of the nanowires. The resulting nanowires show predominantly wurtzite phase; they were up to several micrometers
The energy consumption for unit production of hot metal is lowered. The performance of blast furnace is improved in the tested range mainly due to the decrease in heat requirements for solution loss, sinter reduction and silicon transfer reactions, heat outflow by top gas and wall heat loss.

2014-1-28 · Commercial crucibles are generally made from graphite and clay, or silicon carbide. In the case of clay-graphite crucibles, a long soak at extremely high temperature allows silicon carbide crystals to form in concentrations of approximately 20% of the crucible''s mass, strengthening the crucible and allowing it to survive more severe thermal shock.

2019-5-4 · Synthetic diamond is the hardest known material, where hardness is defined as resistance to indentation. The hardness of synthetic diamond depends on its purity, crystalline perfection and orientation: hardness is higher for flawless, pure crystals oriented to the direction (along the longest diagonal of the cubic diamond lattice).
