Specifications
Stable chemical performanceHigh cold crushing strength
Excellent thermal shocking performances
Good anti corrosion ability
The silicon carbide crucible used the SIC as the primary materials .
It has the the futher of good thermal conductivity,
good high temperature strength,
wear resistant and erosion resistant,
and good thermal shock resistance.
And it is widely applied in lining non-ferrous metal smelting; calcining-endure board,pushing board,and saggar of industrial ceramics;muffle boot of furnace; lining and ignitor of CFBB;lining and ignitor of CFBB; lining if garbage incinerates,etc.
