Silicon nitride - Wikipedia

Silicon nitride is a chemical compound of the elements silicon and nitrogen. Si 3 N 4 is the most thermodynamically stable of the silicon nitrides. Hence, Si 3 N 4 is the most commercially important of the silicon nitrides and is generally understood as what is being referred to where the term "silicon nitride" is used. It is a white, high-melting-point solid that is relatively chemically

Nondestructive Characterization of Beta Silicon Carbide

resistance, chemical vapor deposited (CVD) beta silicon carbide coatings are of interest in tribological and protective appliions. The silicon carbide is formed by a reaction between a silicon halide, such as SiCl4 and a carbon source, such as CH4. The overall reaction is: SiC14 + CH4 ~ SiC + 4 HeI.

than 15000 C (Adamsky and Meor, 1959), the role of beta silicon carbide as the stable low temperature form of silicon carbide was questioned. At temperatures above 20000 C, 2H has never been grown and 3C only rarely. This has caused some researchers to doubt the stability of beta silicon carbide.

differ in the third. Two major polytypes of silicon carbide are alpha silicon carbide ( -SiC) having hex-agonal crystal structure (similar to Wurtzite) and the beta modifiion ( -SiC), with a zinc blende crystal structure (similar to diamond). Thermody-namically -form is marginally more stable than the -form.
