Silicon carbide polishing and grinding powder

Silicon carbide black

The most abrasive grain, with very high quality, hardness (9.2 on the Mohs scale) and durability.

Silicon carbide is characterized by high mechanical strength and extremely high thermal and electrical conductivity. It is an abrasive designed for repeated use.

Application

• for machining hard and brittle materials such as glass, carbide,
• for machining stone (e.g., in gravestone lettering),
• for manufacturing abrasive tools,
• for polishing pastes,
• for lapping valves,
• for the production of embossing products (abrasive papers and cloths),
• for the production of refractory materials,
• as a filler for resin-bonded abrasive products,
• for the manufacture of microwave transistors,
• for coating friction surfaces operating at high temperatures, such as the side surfaces of engine cylinders,
• for the manufacture of nozzles,
• for mechanical sealing,
• for sliding bearings,
• wear-resistant linings.
