Green Silicon Carbide Powder GC Polishing Powder Abrasive Green Diamond Powder 3000 Mesh
Green silicon carbide is produced at high temperatures in a resistance furnace with quartz sand and petroleum coke. It is a synthetic, brittle emery with high thermal conductivity and strength, and does not degrade at 1000°C (7.5 times stronger than aluminum oxide).
Green silicon carbide is characterized by extremely high hardness (Mohs 9.5 / Knoop 2600), second only to CBN and B4C. Haixu Abrasives manufactures high-purity, highly uniform silicon carbide powder. After acid washing and water washing processes, the quality meets FEPA or JIS standards.
Green Silicon Carbide Powder GC Polishing Powder Abrasive Green Diamond Powder 3000 MeshCharacteristics:
1. Low thermal expansion，Strong antioxidant properties。 0-1600The coefficient of thermal expansion at degrees Celsius is7-9 x10-6 /℃。Strong thermal stability。
2. Excellent chemical resistance；It does not readily react with either strong acids or strong bases.。
3. High fire resistance temperature.，Excellent thermal shock resistance.，900The thermal conductivity coefficient at degrees Celsius is0.0130.013 cal/cm2.sec。 Green silicon carbide can be used as a self-bonding ceramic.，Honeycomb ceramic，Foam ceramics and other products。
4. High wear resistance and hardness；High hardness（Mohs 9.5），The self-sharpening property is strong.，Strong grinding force，Suitable for cemented carbide.、Titanium alloy、Polishing and grinding of quartz glass, etc.。
5. High temperature resistance；High-temperature strength。The melting point of green silicon carbide is approximately 2,730°C (2,730 degrees Celsius).2600Celsius，**Operating temperature up to1900Celsius。Apply silicon carbide to the inner wall of the engine.，It can extend the lifespan of the engine.。
