Silicon Carbide coated products (VESCOAT ®) VESCOAT is a product produced by surface-coating high purity graphite material with high purity SiC (silicon carbide). On top of its high oxidation resistance and chemical corrosion resistance, VESCOAT has several excellent soaking properties, size accuracy and flat and smooth surfaces.

Effect of crystallinity of PAN-based carbon fiber surfaces …

Silicon carbide (SiC) coating was synthesized on PAN-based carbon fiber surfaces by reaction of silicon monoxide (SiO) with carbon fibers. The effect of the crystallinity of carbon fiber surfaces on the formation characteristics of SiC coating was discussed. As the crystallinity of carbon fiber surfaces increases, the thickness of SiC coatings decreases from 341 nm to 128 nm and the surface of

Aluminium carbide - Wikipedia

Occurrence Small amounts of aluminum carbide are a common impurity of technical calcium carbide.In electrolytic manufacturing of aluminum, aluminum carbide forms as a corrosion product of the graphite electrodes. In metal matrix composites based on aluminum matrix reinforced with non-metal carbides (silicon carbide, boron carbide, etc.) or carbon fibres, aluminum carbide often forms as an

Silicon Carbide SiC Material Properties - Accuratus

Silicon carbide ceramics with little or no grain boundary impurities maintain their strength to very high temperatures, approaching 1600 C with no strength loss. Chemical purity, resistance to chemical attack at temperature, and strength retention at high temperatures has made this material very popular as wafer tray supports and paddles in semiconductor furnaces.
