3,The main raw materials used in the Impermeable refractory brick are pyrophyllite, bauxite, high-quality clay, calciner and binder.

4,Application parts of products: Aluminum electrolytic cells are generally composed of graphite or silicon carbide working layer, aluminosilicate barrier layer and thermal insulation layer. Anti-permeability brick is the barrier layer, which prevents Na and NaF from penetrating into the thermal insulation layer further.

5.Good feedback of product use effect,the products have been exported to  Australia, Oman, Mexico

6.We are a professional supplier, who can provide customers with free product technology, use and other issues.
