Product Description

High Thermal Shock Resistance Si3N4 Ceramic Rod

Prime characteristics of the Si3N4 Ceramic Rods

1. Extraordinary thermal shock resistance, it can withstand up to 1000℃
2. It's easier to do precise machining, the tolerance of diameter can be 0.001 mm
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 strength are much higher stainless steel
