Acid-Resistant Bricks

Acid-resistant bricks possess excellent corrosion resistance to organic and inorganic acids (excluding hydrofluoric acid), along with good strength and wear resistance. They are widely used in acidic atmosphere flues, autoclaves and recovery boilers in the acid pulping industry, as well as large acid-resistant pool containers and storage tanks.
