Description

General description

Silicon carbide (SiC), also known as carborundum, is composed of silicon and carbon, forming a hard refractory ceramic material that exhibits extreme mechanical and thermal stability. This product is a SiC nanopowder with a particle size less than 100 nm and a high surface area of 70-90 m2/g. Our product is primarily made of the beta phase with approximately 3-15% adopting an amorphous structure. With a Mohs scale hardness of 9.5, silicon carbide is one of the hardest materials, which make its nanopowder useful in the production of abrasives for polishing and grinding and as a coating or composite material for high wear-resistance. SiC nanoparticles are also under research as sensors and imaging nanoprobes for bioscience and clinical diagnosis.

We are committed to bringing you Greener Alternative Products, which belongs to one of the four categories of greener alternatives. This enabling product has been enhanced for energy efficiency. Click here for more information.
