Silicon Carbide Pipe Cone

Short Description:

Sintered alpha silicon carbide pipe tube is produced by sintering ultra-pure sub-micron powder. This powder is mixed with non-oxide sintering aids, then formed into complex shapes by a variety of methods and consolidated by sintering at temperature above 3633 degrees Fahrenheit.

The sintering process results in a single-phase fine-grained silicon carbide that is very pure and uniform, with virtually no porosity enabling the materials to withstand corrosive environments, abrasive environments, and environments operating under high temperature (2552 degrees Fahrenheit). These properties make sintered alpha silicon carbide ideal for applications such as pipe liner , cyclone liner.
