What is green silicon carbide?

Date: 2021-01-14 14:51:04
     Green silicon carbide and black silicon carbide production mode is basically the same, but the requirements of raw materials are different.Green silicon carbide is petroleum coke and high quality silica as the main raw material, add salt as an additive, through the resistance furnace high temperature smelting, smelting into the crystal purity is high, high hardness, its hardness between corundum and diamond, mechanical strength is higher than corundum.The crystal purity is high and the hardness is high.

With black silicon carbide, green silicon carbide manufacturing methods but the purity of raw materials demand is higher, also in the resistance furnace under the high temperature of 2200 ° C to form, green, translucent shape, hexagonal shape, the Sic content is higher in black, physical properties similar to black silicon carbide, but the performance is slightly crispy in black, 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, but also used in semiconductor materials, high temperature silicon carbon rod heating element, far infrared source base material, etc..
