Green Silicon Carbide
Green silicon carbide is made of quartz sand and petroleum coke through high-temperature melting. The smelted crystals have high purity, high hardness and strong cutting force, and are suitable for processing hard and brittle materials. Green silicon carbide is suitable for grinding hard alloys, hard and brittle metals and non-metallic materials, such as non-ferrous metals such as copper, brass, aluminum and magnesium, and non-metallic materials such as precious stones, optical glass and ceramics.
Advantages
1. Large furnace smelting, long smelting time, sufficient crystallization, large crystal particles, high purity and less impurities;
2. Equipped with international advanced Coulter particle size detector;
3. The company's laboratory has been certified by the government's Import and Export Inspection and Quarantine Bureau;
