Brief Introduction
Phosphate refractory brick, also known as phosphate bonded alumina brick. Rongsheng mainly produces ordinary phosphate brick, phosphate bonded wear-resistant brick, special phosphate brick and phosphate composite brick. They have excellent qualities such as strong chemical corrosion resistance, high strength, good wear resistance, excellent thermal shock resistance, high load softening temperature and poor thermal conductivity.
