Experimental Optimization of Annular Polishing …
Machined surface quality has a strong impact on the functionality of silicon carbide-based components and devices. In the present work, we first analytically investigate the complex coupling of motions in annular polishing based on the Preston equation, which derives the influential parameters for material removal. Subsequently, we conduct systematic annular polishing experiments of reaction

Silicon carbide wafers have high thermal conductivity, which means they can transfer heat from one point to another well. This improves its electrical conductivity and ultimately miniaturization, one of the common goals of switching to SiC wafers.
Black silicon carbide CF60
It takes petroleum coke and high quality silicon as raw materials, adds salt as additive, and is fused through the electric resistance furnace at high temperature. Compared with green silicon carbide, black silicon carbide is with slightly lower purity, hardness and brittleness, hexagonal crystalline of microscopic shape, 3300kg/mm3 of microhardness.
Carbure de silicium — Wikipédia
Le carbure de silicium est un composé chimique de formule SiC. C''est une céramique réfractaire ultradure semiconductrice synthétique, qu''on peut trouver dans la nature sous la forme d''un minéral très rare, la moissanite.Grâce au procédé Acheson, depuis la fin du XIX e siècle, on sait produire industriellement de la poudre de carbure de silicium, qui servit d''abord comme abrasif.

Historically, SiC’s Achilles’ heel has been its relatively poor high-volume manufacturability and therefore, producing high-quality SiC crystals was difficult. A large variety of defects such as edge disloions, various types of screw disloions, triangular defects, basal plane disloions and others, could occur in high nuers across even a small-size wafer.
