Brief Introduction
Silicon Carbide Nitride Bonded Brick
Silicon Carbide Nitride Bonded Brick is widely used in as lining bricks of large aluminum electrolytic cell. Silicon Carbide Nitride bonded refractory provides improved thermal conductivity, rapid cooling and increases in tank capacity.On its surface can form alumina and cryolite of eutectic content which can protect the tank lining work layer, prolong the tank's service life,
Advantage:
High thermal conductivity
Excellent cryolite melt and liquid aluminum resistance
High electrical resistivity
Low thermal expansion
Low porosity
