Is silicon carbide powder an insulating material?

Silicon carbide is a high-temperature and high-power semiconductor material in the semiconductor field. However, there is a fundamental difference between silicon carbide semiconductor materials and silicon carbide abrasive materials in the field of grinding. Silicon carbide in the semiconductor industry is a single crystal grown by PVT or HTCVD method. It shows different conductivity with temperature change. In the field of grinding, silicon carbide powder is a silicon carbide polymer produced by high-temperature melting and smelting. It is an insulting material at room temperature and suitable for making silicon carbide functional ceramics.

Black silicon carbide F220 F240 used for abrasive filament

Abrasive brushes made from SiC abrasive filament are suitable for grinding and cleaning difficult-to-clean tubular or porous metal castings. The substrate of abrasive brush wire is nano-modified nylon. It is elastic and gets bending properties. Black silicon carbide is the main material. Mixing SiC abrasive material and Nylon together to produce nylon abrasive filament. Then adopt an abrasive filament to produce an abrasive filament disc or brush. The mostly used grits are black silicon carbide F36-F220 abrasive grain and black silicon carbide powder F240-F400.
