Silicon Carbide (SiC)

Silicon Carbide (SiC), also known as carborundum, is a very hard material widely used for grinding and polishing, in the form of grinding wheels, polishing and grinding powders.

Granular Silicon Carbide is commercially produced by a reaction at a very high temperature. High-quality silica sand and carbon (usually petroleum coke) are mixed in the correct ratio to reaction material. A lot of material is built from this mixture. In the middle of this pile of material is a core of graphite that serves as a current conductor. The graphite core is connected to a transformer and then energized. As a result of the resistance, the temperature in the core of the heap of material (furnace) rises to approximately 2700 degrees Celsius.


As a tread material for mechanical seals, the material has now been used for about 30 years. The material is a ceramic and is grouped under the ‘hard’ treads. Silicon Carbide can be used as a rotor and/or stator depending on the design, applications and other tread material. Contact us now and get information about the different treads and combinations.
