Silicon carbide (SiC) is a synthetic silicon carbide material that rarely exists in nature. It was discovered in 1890 through synthetic experiments. Then, people used quartz sand and petroleum coke (or anthracite) to synthesize silicon carbide through high-temperature smelting. And industrialized mass production of silicon carbide begins. As additives of thermal resistance and anti-corrosion coatings and paint, green silicon carbide powder plays an important role.

Green silicon carbide is an ideal abrasive blasting media and polishing material for copper and brass.

This week, the silicon carbide price continued to decline. At present, the black silicon carbide price of 98% blocks is reduced by about 50 USD per ton compared with last week in Ningxia & Gansu Province.

Black silicon carbide grain is the main abrasive component of coated abrasives, especially sandpaper. It can be used as wear-resistant material on the surface of the skateboard.

As one of the commonly used abrasive materials, silicon carbide(Carborundum) has many advantages in thermodynamics, chemicals, and physics. It is suitable for lapping，abrasives，paints and refractories.  The properties of silicon carbide are demonstrated in the following aspects:

High purity silicon carbide powder has the characteristics of strong oxidation resistance, good high-temperature chemical stability, and corrosion resistance. It is an ideal choice as a silicon carbide ceramic membrane material is made by high-temperature sintering. It can be used as a three-way catalyst for automobiles and a DFP ceramic membrane to filter exhaust gas and diesel particles.
