Black silicon carbide and black aluminum oxide abrasive grit are both hard materials. They are both good abrasive materials in the grinding and polishing industry. But there are differences in their chemical composition and physical properties and so on. Another name for black silicon carbide is black carborundum.  And another name for black aluminum oxide is black corundum.  They are both Synthetic black emery.

In the past month, the silicon carbide price fluctuates to more extent.  Silicon carbide manufacturers quote low prices in May 2023.

Silicon carbide powder is a synthetic material that is resistant to high temperatures, chemical corrosion, air oxidation, and UV aging. So silicon carbide powder works excellent for corrosion protection.

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.
