Product Description

 SIC Coating  Graphite Product/part




1.High purity and high temperature resistance.

2. Coefficient of thermal expansion :4.8×10-6℃-1

3. High speed of heat transfer 80W/m·k


5.No abnormalities dip in the 98% sulfuric acid solution for 8 hours.

6.No abnormalities dip in the 30% sodium hydroxide solution for 8 hours.

7.No abnormalities heat 1600℃ in the air for 8 hours.


Product Description:


The SiC coating releases C and Si, fuses them together and wraps up the graphite products to make a protective layer. The new SiC coating bonded up the graphite products closely will produce special and superior properties. Due to the artificial graphite substrates, they are easy to be processing and molding. And they are widely used in metallurgy mold, electronic semiconductor four piece mold, smelting crucible, impeller under the condition of high temperature etc. With this coating on the surface, the graphite mold has the much longer working life than normal graphite mold.
