Wear-resistant refractory brick is made of industrial phosphoric acid, industrial aluminum hydroxide as aluminum phosphate solution as a binder, the molar ratio of Al2O3: P2O5 = 1: 3: 2. The aggregate used is the same as the phosphate refractory bricks. In the use of refractory bricks, with the same salt-resistant refractory brick to form a quartz-type orthophosphate-based binder.
