Nitride Bonded Silicon Carbide (N-SIC/Si3N4-SIC/NBSIC)

This material has an open porous structure with approx 12 to 15% porosity. 

Comparing this to the R-Sic material, the individual pores are smaller. 

In applications involving high temperatures, the surface is covered by a very thin glass layer.the ceramic component is thus proteced from further oxidation by this glass layer. Consequently N-Sic ceramic can be used for highly stressed kiln parts.Tangshan HanWei is your right choice regarding SIC ceramics issue.Powered by Tangshan HanWei Trading Co.,Ltd.
