DETAILS

1. Phosphate high alumina bricks are made of high alumina bauxite clinker as aggregate and subdivision, phosphoric acid or aluminum phosphate as geometric grade, semi-dry pressed, 400°C---600°C heat treatment made of high alumina Refractory products.
2. The product is divided into two codes according to the bonding agent: P and PA.
P-phosphate is combined with high-aluminum refractory brick (referred to as phosphate refractory brick), and the binder is a phosphoric acid solution having a concentration of 42.5%--50%.
PA-phosphate combined with high-aluminum wear-resistant brick (abbreviated as wear-resistant brick), the binder is a solution of industrial phosphoric acid and aluminum hydroxide, the molar ratio is: Al2O3: P2O3=1:3.2
3. Characteristics: low refractoriness, but high strength and good thermal shock resistance, mostly used in grate coolers, kiln hoods, etc.
