2. Description
Taking silicon carbide as the main material and adding expansion
agent and anti oxidant, SIC silicon carbide ceramic kiln plates or
slabs for household porcelain firing 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.
3.Property:
Good thermal shock resistance
Good resistance against corrosion and oxdiation
Good mechanical strength at high temperature
Excellent thermal and electric conductivity
Long service life and energy saving
Environmental friendly
Other recommendations
