Phosphate bonded high alumina brick is a kind of high-quality refractory material used in high-temperature industrial fields.

It uses high-purity bauxite clinker as the main raw material. This raw material has the characteristics of high temperature resistance and hardness. Then, phosphates (such as phosphoric acid or aluminum phosphate) are used as binders to firmly bond the bauxite clinker particles together. In the production process, after procedures such as mixing and molding, it will be fired in a high-temperature environment to make the brick body reach a high density and strength.

Phosphate bonded high alumina brick has a series of excellent properties. It has outstanding high temperature resistance and can maintain stable physical and chemical properties in a high-temperature environment, and is not prone to deformation or melting. At the same time, it has high mechanical strength and can withstand large pressure and impact force, and is not easy to be damaged. In addition, this kind of brick also has good thermal shock resistance. In the case of a sharp change in temperature, it can still maintain the integrity of the structure and is not prone to problems such as cracking. Due to these characteristics, phosphate bonded high alumina bricks are widely used in various high-temperature industrial furnaces, heating equipment, etc., providing reliable refractory and heat insulation protection for them, prolonging the service life of the equipment, and ensuring the safety and stability of the production process.
