The main component of acid-resistant brick is silicon dioxide, which, when fired at high temperatures, forms a large amount of mullite, substances with high acid resistance. Because acid-resistant bricks have a dense structure and low water absorption, they can also be used at room temperature. Resistant to alkaline media of any concentration, but not resistant to high temperature melt alkali.
