Green Silicon Carbide

Green silicon carbide (SiC), produced through a sophisticated electric arc furnace process, is a premium abrasive renowned for its hardness and purity. With a Mohs hardness of approximately 9.5, it exhibits exceptional strength, wear resistance, and superior thermal conductivity. As a result, this material is ideally suited for a range of demanding applications, from abrasives to high-performance ceramics.

Processed into various shapes and grit sizes, green silicon carbide meets diverse industrial needs, ranging from large grains to ultra-fine powders. Primarily, it plays a key role in the production of refractories, advanced ceramics, and cutting tools. Additionally, it is used extensively in grinding wheels, sandpaper, and blasting mediums for surface preparation.

Moreover, its applications extend to the semiconductor industry, where it is essential for wafer fabrication. It is also utilized in electronics, particularly in power devices that operate at high temperatures. At Lane Abrasives, we offer green silicon carbide in a variety of standard grit and powder sizes, with the option to customize based on specific customer needs. Due to its minimal impurities and remarkable thermal stability, green silicon carbide is indispensable for high-performance applications.
