Different Sizes Wear Resistance High Purity Alumina Ceramic Plate
Description:
1. Withstand high temperature: with high melting point, high boiling point characteristics, can be used under high temperature is not affected.
2. Not easy to corrode: not affected under strong acid, strong alkali, inorganic and organic salt conditions.
3. Antimagnetic: Because the product material is non-magnetic, it does not absorb dust, which can reduce surface peeling.
4. Electrical insulation: it is an insulator at room temperature with high resistivity, which can be used in equipment requiring insulation.
