Product detail
Fused Zirconia Mullite
Main Composition:SiO2 + Al2O3+ZrO2
Application:New type steel casting
Capacity:3000 tons per month
Raw Material:Zirconia sand
Package:Export ton bag
Product Introduction
Fused Zirconia Mullite is made by the fusion of high-quality zirconia sand and industry alumina powder in the electric arc furnace. Adding zirconium can improve the chemical resistance, heat shock resistance and reduce the expansion coefficient of mullite.
Features
1.Good chemical resistance.
2.Good thermal shock resistance.
3.Low expansion coefficient.
Application
Zirconium mullite is mainly used for new-type steel casting slides, sizing nozzles and shrouds of continuous casting ladle, and key parts of glass furnaces.
