Phosphate Bonded Alumina Brick - High Alumina Refractory
For example, in the aggregate particle composition of phosphate bricks, a considerable amount of 5 ~ 10mm of alumina is adopted so the apparent porosity of brick is larger. After treated at the same temperature, the modulus of elasticity of the brick is much lower than that of the wear-resistant brick, and the thermal shock resistance is good.
