Engineering Ceramics Co., Ltd. is a Nitride Bonded Silicon Carbide Bricks manufacturer and suppliers in China. We have cooperated with LIRR, whom is the largest Nsic Bricks manufacturer in China and also the largest in the world, get over 40% world market share, 30,000 tons annual production capability, provide the full technology and raw materials to us.
Nitride Bonded Silicon Carbide bricks is widely used in as lining brick of large aluminum electrolytic cell, as high performance refractory, the bricks 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.
High thermal conductivity
Excellent cryolite melt and liquid aluminum resistance
High electrical resistivity
Low thermal expansion
Low porosity
