    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
