(Sterling), a subsidiary of Uniroyal Technology Corporation (Nasdaq: UTCI), has begun installation of additional silicon carbide (SiC) production equipment that is expected to increase its SiC wafer production by a factor of ten when the build out is completed in 2001.
2009/1/28· In the last decade, superconductivity was found in doped silicon clathrates [2–4] crystallizing in a covalent tetrahedral sp 3 network with a bond length similar to that in diamond. In 2004, type-II superconductivity was found in highly boron-doped diamond (C : B) [ 5 ], the cubic carbon modifiion with a large band gap.

SILICON CARBIDE PRODUCED NO FIBROSIS OF LUNGS IN NORMAL EXPERIMENTAL ANIMALS, BUT PROFOUNDLY ALTERED THE COURSE OF INHALATION TUBERCULOSIS, LEADING TO EXTENSIVE FIBROSIS & PROGRESSIVE DISEASE. INERT REACTION RESULTED WHEN SILICON CARBIDE WAS INJECTED IP IN GUINEA PIGS.
Chemical classifiion of carbides Carbides can be generally classified by the chemical bonds type as follows: (i) salt-like (ionic), (ii) covalent compounds, (iii) interstitial compounds, and (iv) "intermediate" transition metal carbides. Examples include calcium carbide (CaC 2), silicon carbide (SiC), tungsten carbide (WC; often called, simply, carbide when referring to machine tooling
Silicon nitride (Si3N4) is a chemical compound of the elements, silicon and nitrogen. It is one of the leading technical ceramic materials available on the market and has similar properties like silicon carbide. Silicon nitride (Si 3 N 4) is a chemical compound of the elements, silicon and nitrogen.

A study of the dependence of the electronic structure and energetic stability on the chemical surface passivation of cubic porous silicon carbide (pSiC) was performed using density functional theory (DFT) and the supercell technique. The pores were modeled by removing atoms in the  direction to produce a surface chemistry composed of only carbon atoms (C-phase). Changes in the electronic
