High strength silicon nitride ceramic ring

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
