Fused cast High Zircon Brick
The series of GJ-Zare fused cast high zirconia refractories. They are made of artificial synthesis of high purity raw materials through special casting process.
The crystalline texture is consisting of baddeleyite. So the characteristics of these products are excellent corrosion resistance and very low blister and stoning potential. These advantages can prevent liquid glass from pollution effectively. GJ-Z can be used in a wide range of glass furnaces,especially high quality and special glass furnaces such as TV glass, Borosilicate glass,
Cover glass, Aluminosilicate glass, Halogen lighting glass, Opal glass and Fiber glass.
GJ-Z are mainly consisting of GJ-Z88-WS and GJ-Z95-WS,and used in sidewall,throat cover,throat support,electrode block and dam block ect.
