SiC (silicon nitride ceramics), silicon carbide (SiC) ceramic material as a main component . SiC strength is high, especially hot silicon carbide, is the world's one of the hardest substances . It is a very high temperature , the intensity has been able to maintain a high temperature to 1200 ℃without drop , heat will not melt into the melt until 1900 ℃to decompose , and have an amazing resistance to chemical corrosion , resistant to almost all inorganic acids and 30 % or less of the caustic soda solution , but also the ability of many organic corrosion ; but it is also a high-performance electrical insulation materials.
Silicon carbide ceramic ball is in a non- oxidizing atmosphere precision ceramic high-temperature sintering , high strength, high wear resistance, high temperature resistance , corrosion resistance, acid and alkali, long-term use in the sea , and has absolute power absolutely excellent magnetic performance. At 800 ℃, the strength , hardness is almost constant , having a density of 3.20g/cm3, bearing steel is almost 1 /3 of the weight of a small centrifugal force when rotating can achieve high-speed operation . Also has a self -lubricating, it can be used without lubrication medium to high pollution of the environment. Become ceramic bearings, hybrid ceramic ball bearings preferred beads .
Commonly used in the production of ceramic balls of silicon nitride (Si3N4), silicon carbide (SiC), alumina (Al2O3) and zirconia (ZrO2). In these four ceramic materials bearing ball, Si3N4 best overall performance. Si3N4 with high temperature resistance, corrosion resistance, electrical insulation, non-magnetic, high-strength, low density and other properties.
