®   Features

SiC series is high-density product made of silicon carbide fireproofing materials and successfully overcomes the original limitation of previous fireproofing materials. SiC series products can used for oxidation and reduction firing.

®   Application

-              Kiln furniture for ceramics firing.

-              Kiln furniture for electronic parts and magnetic material.

-              Bottom board and fireproof board for high temperature kiln.

-              Inner lining of soaking furnace for non-ferrous metal.

-              Oxidation and reduction firing.

-              Structural materials for high-temperature kiln.
