Descripción

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.
