Product Introduction
Magnesia brick is a kind of alkaline refractory material with magnesia (magnesium oxide) as the main raw material. Magnesia brick has high melting point, high temperature strength, good chemical corrosion resistance and thermal stability, so it is widely used in steel smelting, non-ferrous metal smelting, chemical industry, building materials and other industries.
