Silicon nitride ceramics

‌ Silicon nitride ceramic ball ‌ is a kind of precision ceramics sintered at high temperature in non-oxidizing atmosphere, with high strength, high wear resistance, high temperature, corrosion resistance, acid and alkali resistance and other excellent properties. Its density is 3.20g/cm³, about 1/3 of the weight of bearing steel, small centrifugal force when rotating, suitable for high-speed operation. In addition, silicon nitride ceramic balls are also self-lubricating, suitable for non-lubricating media and high pollution environment ‌ MATERIAL : Si3N4 DENSITY  : 2.8 COLOR  : Black / Blue / White HRDNESS(Mohs scale) : 9 MAX WORKING TEMPERATURE : 1650

silicon nitride ceramic substrate is a kind of high performance and high stability ceramic substrate material, mainly composed of silicon nitride powder synthesized by silicon and nitrogen elements adding a small amount of oxides and rare earth sintered ‌‌. It has the advantages of high hardness, high strength, low thermal expansion coefficient, low creep at high temperature, good oxidation resistance, high thermal corrosion performance, low friction coefficient, etc. ‌ is one of the best structural ceramic materials with comprehensive performance MATERIAL : Si3N4 DENSITY  : 2.8 COLOR  : Black / Blue / White HRDNESS(Mohs scale) : 9 MAX WORKING TEMPERATURE : 1650

Silicon nitride ceramic bolt ‌ is a kind of bolt made of silicon nitride (Si3N4) material, which has excellent high temperature resistance, corrosion resistance and mechanical properties. Silicon nitride ceramic bolts perform well at high temperatures, maintain high strength at 1200 ° C, and only break down at 1900 ° C ‌. In addition, it also has good chemical resistance, able to resist almost all inorganic acids (except hydrofluoric acid) and less than 30% caustic soda solution ‌ MATERIAL : Si3N4 DENSITY  : 2.8 COLOR  : Black / Blue / White HRDNESS(Mohs scale) : 9 MAX WORKING TEMPERATURE : 1650

Silicon nitride ceramic rods perform well in high temperature environments, have good heat shock resistance, and can maintain high strength and impact resistance at high temperatures. Its decomposition temperature is 1800℃ in the air, up to 1850℃ in nitrogen, and it will not break after being heated in cold water at 1000℃ ‌. Silicon nitride ceramics have high thermal conductivity and low coefficient of thermal expansion, which makes them have excellent heat shock resistance at high temperature ‌ MATERIAL : Si3N4 DENSITY  : 2.8 COLOR  : Black / Blue / White HRDNESS(Mohs scale) : 9 MAX WORKING TEMPERATURE : 1650

Silicon nitride ceramic rings are usually manufactured by ‌ hot press sintering process ‌. This process sintering silicon nitride powder under high temperature and high pressure conditions significantly improves the density and mechanical properties of the material. By optimizing the hot press sintering process, the overall performance of silicon nitride ceramic rings can be further improved, making it more suitable for harsh industrial needs ‌ MATERIAL : Si3N4 DENSITY  : 2.8 COLOR  : Black / Blue / White HRDNESS(Mohs scale) : 9 MAX WORKING TEMPERATURE : 1650
