Our company produces high-strength impermeable castables for aluminum electrolytic cells, using carefully selected aluminosilicate raw materials along with composite binders and various additives. When applied to the side walls of the aluminum electrolytic cell, the liquid electrolyte that seeps through the gaps in the carbon bricks reacts to form a dense glassy nepheline, which prevents further infiltration. This material features high strength, low bulk density, low thermal conductivity, and ease of application.
