Product Details

Gold Melting Crucible Graphite Refractory Material

Product Description

The silicon carbide brick used the SIC as the primary materials .

It has the the futher of good thermal conductivity, good high temperature strength, wear resistant and erosion resistant, and good thermal shock resistance.

And it is widely applied in lining non-ferrous metal smelting; calcining-endure board,pushing board,and saggar of industrial ceramics;muffle boot of furnace; lining and ignitor of CFBB;lining and ignitor of CFBB; lining if garbage incinerates,etc.
