CeramTec Rocar® S Silicon Carbide, SSiC

The various types of Rocar include sintered and silicon infiltrated silicon carbide. SSiC is resistant to all chemical media. Since no metallic silicon is present in the matrix, it can be used at temperatures up to 1600°C without impaired strength. Vendors:

Review article: silicon carbide. Structure, …

Although the solubility of these impurities in silicon carbide is reported to be very low (<0.3%, [49, 50]), very limited information exists regarding the likely atomic positions of such solute atoms in SiC framework, that is whether the solutes are accommodated interstitially or substitutionally or whether, for example, local boron carbide or silicon nitride groups are formed.

Carbide Types in Knife Steels - Knife Steel Nerds

15.07.2019· Silicon carbide has a similar hardness to those hard carbides but is not clearly harder, and in general silicon carbide is not as good at cutting steel as aluminum oxide. CBN and diamond are significantly harder than any of the carbides so they are generally better at least in terms of grinding and polishing high wear resistance steels with hard carbides.
