Silicon Carbide (SiC)

Silicon carbide (SiC) is a hard, covalently bonded light grey solid that is nearly as hard as diamond. It is a refractory material (high melting point) with excellent thermal conductivity and low thermal expansion. It displays good thermal shock resistance, corrosion resistance, and stiffness. Silicon carbide is a semiconductor.
Purities Available

Various purities are available from a low purity metallurgical grade black (88 – 92%), to 99.0% (abrasive grade black), 99.2% (black), 99.5% (dark green), 99.7% (light green), and up to 99.9995% for sputtering targets

Typical Applications

Silicon carbide is used to manufacture abrasives, grinding wheels, and metal-cutting tools. It is used in refractories, brake linings, heating elements, and thermistors. It is also used in semiconductor technology.

Packaging Options

Drums, bags, super sacks, & loose bulk


Silicon Carbide TSCA (SARA Title III) Status: Listed

Silicon Carbide CAS Number: 409-21-2

Sustainable Qualities

Silicon Carbide is a highly sustainable material used in various applications, including electronics, abrasives, and ceramics. Made from silicon and Carbon, Silicon Carbide is abundant in the earth’s crust and can be easily sourced. Additionally, Silicon Carbide is highly recyclable, making it an excellent candidate for a circular economy. By recycling Silicon Carbide, manufacturers can reduce their dependence on virgin materials, conserve resources, and reduce waste.
