Black Silicon Carbide Abrasive
Product Number:
The main raw materials of the black silicon carbide abrasive include quartz sand, petroleum coke and quality silica. The black silicon carbide abrasive is made by means of smelting in high-temperature resistance furnace, possessing good hardness (between corundum and diamond), higher mechanical strength than corundum, crisp and sharp characteristics.
The artificial abrasive is extensively applicable for abrasive tool, electronic product cutting and grinding, refractory material, special ceramics, foamed ceramics, modifying agent for coating, plastic and rubber, military and aviation industry, steelmaking desoxidant, etc.
