Phosphate-Bonded High Alumina Bricks

Based on their characteristics, phosphate-bonded high alumina bricks are mainly classified into phosphate-bonded high alumina bricks, phosphate-bonded wear-resistant bricks, and special phosphate bricks. They feature high strength and a dense structure. Phosphate-bonded high alumina bricks offer good thermal shock resistance, while phosphate-bonded wear-resistant bricks provide excellent wear resistance. Special phosphate bricks combine the advantages of both and have high refractoriness under load. They are widely used in waste incinerators, boilers, and rotary kilns.
