FUNCTION: 1. Alumina ceramic plate is a special ceramic plate made from AL, O, ZrO2 as the main raw material, rare metal oxides as flux, and calcined at over a thousand degrees. 2. With high melting point, high hardness, and excellent wear resistance. 3. The hardness of the ceramic patch is second only to diamond, and the surface is smooth and friction-free. 4. Ceramic materials outperform other metallic materials in high-temperature oxidizing or corrosive media. 5. Commonly used in coal crushing, transport systems, grinding systems, dust removal systems, etc., for power generation, steel, melting, machinery, coal, mining, chemicals, cement, ports, and other industries. 6. Suitable for high-power equipment, ICMOS tubes, IGBT patch insulation, high-frequency power supply communication, mechanical equipment, high current, high voltage, high temperature, and insulation parts requiring heat conduction. 7. 28W/m.k thermal conductivity, excellent heat conduction. 8. 15kv/mm insulation performance, high resistance to electrical insulation, safer to use. 9. Alumina material, high hardness, high melting point, wear-resistant.
