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.
Our products mainly have below
