Silicon carbide ceramic not only has excellent mechanical properties at room temperature, such as high bending strength, excellent oxidation resistance, good corrosion resistance, high wear resistance and low friction coefficient, but also outstanding mechanical properties (strength, creep resistance) at high temperature. Silicon carbide ceramic is widely used in automobile, mechanical and chemical industry, semiconductor, space technology, microelectronics, energy, papermaking and other fields, which has become an irreplaceable wear resistant and refractory material.

Product detail
Silicon carbide ceramic (SiC), a non-oxide ceramic, is an extremely hard material with a Mohs hardness of up to 9.5. It exhibits excellent mechanical properties at room temperature, including high bending strength, exceptional oxidation resistance, good corrosion resistance, high wear resistance, and a low friction coefficient. Moreover, Silicon carbide retains outstanding mechanical properties, such as strength and creep resistance, at high temperatures, with a high temperature strength that can be maintained up to 1600°C. These properties make silicon carbide ceramic the best among all ceramic materials. Additionally, it boasts superior oxidation resistance compared to other non-oxide ceramics.
Silicon carbide ceramic finds widespread applications in various industries, including automotive, mechanical, and chemical industries, semiconductors, space technology, microelectronics, energy, papermaking, and more. It has become an ideal material for harsh conditions involving high temperatures, high pressures, corrosion, and abrasion.
Mascera produced silicon carbide ceramics in two forms, sintered silicon carbide (SSiC) and reaction bonded silicon carbide (SiSiC).
Sintered silicon carbide ceramic is made of high-purity and nano-grade raw powders and sintered at a high temperature of 2100℃-2200℃, the sintering process will densify the green body and cause shrinkage approximately 20%; reaction boned silicon carbide uses micron-sized silicon carbide powder, the sintering temperature is 1450℃-1700℃, there is no shape shrinkage during sintering. The higher sintering temperature makes sintered silicon carbide having better performance, such as higher density, higher strength, better resistance to oxidation and corrosion; for applicatons which don't have so high properties requirement, reaction bonded silicon carbide is more cost effective.
