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.

Recently at the bottom of September, the black silicon carbide price raised a lot because of the new round environment protection season and lack of electricity supply.

In many industries such as construction, petrochemical, high-temperature materials, and energy industries, many products need to achieve corrosion resistance, high-temperature resistance and wear resistance. To achieve this goal, it is usually necessary to add special materials to the coating or paint. Carborundum powder is just the one to meet all function needs.

Black silicon carbide grain & black silicon carbide powder are widely used as sandblasting grit, polishing powder, and raw material for coated abrasive tools. High-quality black silicon carbide grain is durable of good grinding ability for those applications.

Silicon carbide is a sharper and harder grain than aluminum oxide, but silicon carbide is less durable because it is brittle and has a narrower shape that wears out faster. Due to its razor sharp grains, silicon carbide will have no problem easily cutting glass, plastic and metal under light pressure. However, hardwoods and metals
