Zircon brick ZS 64 made from stable zircon sand is a kind of great refractory brick with the zircon content over 64 %. It is acid refractory with the advantages of high mechanical strength, high refractoriness under load, excellent thermal shock stability, good creep resistance and good corrosion resistance to glass liquid. It is widely used in the high erosive zones of glass furnace, chemical industry, and metallurgy industry.
Specifications and Applications
1,High mechanical strength
2,Excellent thermal shock stability
