A monolithic SiC ceramic and two SiC–C composite ceramics containing 10 and 20 vol% graphite were fully densified with Al 4 C 3 and B 4 C as additives. The tribological properties of these materials were evaluated by sliding against sintered silicon carbide under
Silicon carbide (SiC) is a synthetic, semiconducting fine ceramic that excels in a wide cross-section of industrial markets. Manufacturers benefit from an eclectic offering of silicon carbide grades due to the availability of both high-density and open porous structures.
A silicon nitride body with closed porosity is isostatically pressed (uniform pressure on all sides) via an inert gas at up to 2000 bar while the chaer is simultaneously heated. This process effectively squeezes any pores/defects from the material while it is sintering and brings the density closer to …

Silicon carbide is second only to diamond and boron carbide, and its hardness is up to HRC60-65. It has high wear resistance and is therefore used for sliding parts (mechanical seals, etc.). In addition, it has a high Young''s modulus and a small coefficient of thermal expansion, and is therefore used for high-precision components (optoelectronics, substrates, aerospace technology, etc.).。
