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

Specification of high purity Alumina Ceramic rods

Raw material Silicon nitride (Si3N4), Alumina (Al2O3), Zirconia (ZrO2) and Silicon carbide (SiC) optional
Dimension capability Diameter range from 0.30 ~50 mm, length can be up to 1000 mm
Secondary process Lapping, Fine grinding, Precision cutting, Tapping, Drilling and so on
Technical parameters Diameter can be with 0.005 mm, length can be with 0.10 mm, roundness can be 0.001 mm
Roughness The cylinder surface can be polished to mirror-like affect, roughness to be Ra 0.10 or better
Surface treatment Polished to be diamond - like surface, Glazed, Metalized for ceramic to metal boning
Cosmetic quality Smooth surface free of contamination, no deformation, and crack
