Silicon nitride ceramic insulating substrate

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
