Si3N4 silicon nitride ceramic spacer

Silicon Nitride (Si3N4) Characteristics:
1 Good thermal shock resistance
2 Creep resistance
3 Low density
4 High fracture toughness
5 High hardness and wear resistance
6 Electrical resistivity

The prime features of  Si3N4 Silicon Nitride Ceramic

1. Extraordinary thermal shock, it can withstand up to1000ºC
2. It’s easier to do precise machining, the tolerance can be 0.001mm
3. Chemical corrosion resistance under high temperature, except for HF and H3PO4
4. Extreme wear and abrasion resistance., much better than stainless steel
5. Great mechanical properties, hardness, compressive and flexural strength are much higher stainless steel
