2000/7/25· Silicon carbide (SiC) porous substrates are prepared by pressureless sintering of SiC powders under an inert atmosphere of argon. The porous SiC substrates were characterized by measuring their porosity, pore size distribution, surface characteristics, and structure. Their transport characteristics were investigated using N2 and He as the test gases. Three different starting powders …

Silicon nitride-silicon carbide composite powders are prepared by carbothermal reduction of crystalline silica powder, carbon powder and, optionally, crystalline silicon nitride powder. The crystalline silicon carbide portion of the composite powders has a mean nuer diameter less than about 700 nanometers and contains nitrogen.

Silicon nitride is a chemical compound of the elements silicon and nitrogen. Si 3N 4 is the most thermodynamically stable of the silicon nitrides. Hence, Si 3N 4 is the most commercially important of the silicon nitrides[4] when referring to the term "silicon nitride". It is a white, high-melting-point solid that is relatively chemically inert
ULTRONTM - Sintered Silicon Carbide (SSiC) is produced using very fine silicon carbide powder containing sintering additives and is processed using forming methods typical for other ceramics and sintered at 2,000 to 2,200 C in an inert gas atmosphere.
In Automotive appliions, sintered Silicon Carbide has been used in appliions such as seal pump faces. The surface of sintered SiC, when lapped or polished for sealing to another surface, must be free of blemishes and mechanical defects. Lapping and polishing processes therefore must be well defined and controlled assuring minimal variation and production scrap. In this study, we related
