The high-strength anti-spalling alumina-phosphate brick uses high-purity bauxite and mullite as its main raw materials; after phosphating treatment it is sintered at high temperature. It features high strength, low porosity and good thermal shock resistance. It is an ideal product for the preheating and calcining zones of cement kilns, and the best matching product for rotary kilns calcining high-moisture materials, the reaction zone of zinc oxide rotary kilns, the high-temperature zone of waste-incineration rotary kilns, lithium carbonate rotary kilns, aluminium-dross rotary kilns and hazardous-waste rotary kilns. It is also a functional product independently developed by our company.
