Silicon Carbide (artificial): Mineral information, data and …
Artificial silicon carbide (SiC) is included in this database as samples of it are frequently sold in "rock shops" and on internet auctions, sometimes under the name ''carborundum'', sometimes as ''moissanite'' (there is a very rare natural silicon carbide mineral with the name moissanite), but most frequently with no name at all.
A Kinetic Study of the Chemical Vapor Deposition of …
2019/12/6· Silicon carbide (SiC) films were prepared from dichlorodimethylsilane (DDS) precursors at temperatures ranging from 1173 to 1373 K by atmospheric pressure chemical vapor deposition (VD). A comprehensive model of the chemical vapor deposition of SiC from DDS was developed, which includes gas‐to‐surface mass transfer, surface sticking, and gas‐phase chemistry.

businessIndustry Information Silicon Carbide Silicon carbide, also known as carborundum, is a ceramic product made up of silicon and carbon atoms bonded in a crystal lattice. It has the chemical formula SiC. It was first discovered by a young scientist named Dr
ICSC 1061 - SILICON CARBIDE (non-fibrous)
This card does not apply to silicon carbide in "fibrous" or "whisker" form. There is evidence of fibrosis in mixed dust situations, the risk of which is enhanced in persons with tuberculosis. There is no evidence that silicon carbide (non-fibrous) causes fibrosis in the absence of other dusts.

Silicon Carbide (SiC) Properties and Appliions
Silicon carbide is a hard covalently bonded material predominantly produced by the carbothermal reduction of silica (typically using the Acheson process). Several commercial grades of silicon carbide exist such as nitride bonded, sintered, reaction bonded, SiAlON bonded and clay bonded.
Basic Parameters of Silicon Carbide (SiC)
Silicon carbide crystallizes in numerous (more than 200 ) different modifiions (polylypes). The most important are: cubic unit cell: 3C-SiC (cubic unit cell, zincblende); 2H-SiC; 4H-SiC; 6H-SiC (hexagonal unit cell, wurtzile ); 15R-SiC (rhoohedral unit cell).-SiC (rhoohedral unit cell).
Effects of Surfactants and Surface Treatment on Aqueous …
The effects of the addition of surfactants and of the surface treatment upon the aqueous dispersion of silicon carbide were examined. In the case of β-SiC, the addition of nonionic surfactants having relatively longer lengths of hydrocarbon and oxyethylene chain to the β-SiC treated with a silane coupling agent enhanced the dispersion stability.
Silicon carbide - Substance Information - ECHA
The molecular formula identifies each type of element by its chemical syol and identifies the nuer of atoms of each element found in one discrete molecule of the substance. This information is only displayed if the substance is well–defined, its identity is not claimed confidential and there is sufficient information available in ECHA’s databases for ECHA’s algorithms to generate a
