The Girts of Acid washed black silicon carbide for SiC Expoxy are black silicon carbide #320, #90, #60, and #12. SiC Epoxy is a new type of polymer composite material. It has characteristics including high strength, low density, high thermal conductivity, high-temperature corrosion resistance, fire resistance, non-conductivity, and easy processing. Epoxy resin silicon carbide is a modified resin material with the addition of black silicon carbide and other additives. The superior performance comes from the raw material SiC grits. 

Black Carborundum F020 F016 plays an important role in ductile iron casting. It can replace ferrosilicon as an Oxygen scavenger, inoculant and nebulizer in the metallurgical industry. The following are the main functions of black silicon carbide in ductile iron casting:

Silicon carbide is not only an excellent refractory material. But also it is a commonly used grinding material, anti-corrosion material, and thermally conductive material. The main chemical of silicon carbide is SiC, with another name carborundum. It gets many excellent properties.

Silicon carbide powder is famous for its high refractory temperature, hardness, and chemical stability. At the same time, the thermal conductivity of silicon carbide is also an important reference index for many related applications. The thermal conductivity of high-purity silicon carbide crystals is 1490 W/M · K. The thermal conductivity of silicon carbide obtained through high-temperature smelting varies with temperature. The higher the temperature, the lower the thermal expansion coefficient. Overall, the thermal conductivity of silicon carbide ranges from 60 to 200 W/M · K. After making silicon carbide ceramics, the thermal conductivity is about 40-220W/M · K. The thermal conductivity of silicon carbide powder is several times that of corundum.

Recently, the research team of the Laboratory of Precision Optical Manufacturing and Testing Center of Shanghai Institute of Optics and Precision Machinery, Chinese Academy of Sciences, has made progress in the research on improving polishing efficiency by femtosecond laser modification of silicon carbide surface.
