The main component of acid-resistant brick is silica, which forms a large amount of mullite when roasted at high temperatures, which is a substance with high acid resistance. Because the acid-resistant bricks have a tight 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 molten alkali.
