Green silicon carbide production process

 In the metallurgical production we commonly see silicon carbide resistance has green silicon carbide and black silicon carbide two different colors, today to introduce two different colors of silicon carbide production mode: green silicon carbide and black silicon carbide production mode is basically the same, but the requirements of the raw materials are different.Green silicon carbide is based on petroleum coke and high quality silicon dioxide as the main raw materials, plus salt as additives, through the resistance furnace high temperature smelting, smelting into crystal purity, high hardness, its hardness between corundum and diamond, mechanical strength is higher than corundum.The crystal purity is high and the hardness is high.

Black silicon carbide , green silicon carbide manufacturing method but the purity of raw materials required higher, in the form of resistance furnace 2200°C at high temperature, green, translucent shape, hexagonal shape, black silicon carbide content is higher, physical properties similar to black silicon carbide but its performance is slightly black brittle, but also has good thermal conductivity and electrical properties.

The main uses of green silicon carbide are: green silicon carbide, suitable for processing hard alloy, glass, ceramics and non-metallic materials, can also be used for semiconductor materials, high temperature silicon carbon rod heating elements, far infrared source base material, etc..
