sic ceramic foam filter made in China
High strength
Low thermal expansion coefficient
Good thermal conductivity and thermal shock resistance
Good resistance to liquid aluminum erosion capability
High erosion
2. Applications of sic ceramic foam filter
Widely used in large aluminum electrolytic cell of lining material. In the electrolytic aluminium industry, because of nitride bonded silicon carbide products can be made thin wall lining, enlarge the tank capacity, improve the thermal conductivity, can rapid cooling, and they are permitted to enter a higher power, increase the tank production capacity, at the same time, in its surface can form alumina and cryolite of eutectic content, in order to protect the tank lining work layer, prolong service life, therefore, this product is aluminum industry generally welcome.
