99% Alumina Refractory Ceramic Sagger High Temperature Resistance
Alumina Ceramic Sagger Refractory Kiln Furniture High Temperature Insulation Performance
Ceramic Refractory Plate / Kiln shelves for industrial kiln furniture as the main material and adding expansion agent and anti oxidant,oxide bonded silicon carbide SIC shelves used for Sanitary ware kiln have very high load softening temperature and excellent anti oxidative effect through vibration supported uniaxial press compaction and high temperature firing. It was originally used as an alternative to conventional bonded SiC materials, but it shows the long term stability comparable to RSiC and NSiC with lower cost.
