Description for Acidic Refractory

Acidic refractories include substances such as zirconia, alumina, silica and fire clay brick refractory. The most commonly used acid resistant brick are Silica Brick and Fireclay Brick.

Silica brick is a kind of silica product with over 93% SiO2 content. Its raw materials are silica and waste silica brick. It has strong resistance to acid slag erosion and high refractoriness under load that is close to its refractoriness. There will not bulk shrink after reheating, but a little expanse. Silica brick is easy affected by alkali slag erosion. Silica brick is mainly used in heating equipments of coke oven, glass furnace and acid steel-melting furnace.
