Hosphate- bonded high-alumina brick
Hosphate-bonded high-alumina brick is a refractory product made of high-quality high-alumina clinker as the main raw material, using phosphoric acid or aluminum phosphate as a binder, mixed at a certain ratio, and then press-molded and heat-treated at 400 ° C to 600 ° C. . According to the physical and chemical indicators are divided into P, PA two brands. Mainly used in cement and other industrial kilns.
