1.Definition:
It is the fire resistant products which is made of the industry alumina powder and well-selected zircon sand as the raw material, and the zirconia content range from 33%-45%.
2.Raw materials:
industry alumina powder and well-selected zircon sand3.Production
3.Production technology: sintered.
4.Highlight:
Comparing with the electric smelting zirconia corundum Bricks,even-textured, no shrinkage, so has fine erosion stability of the glass liquid resistance, even thermal expansion, and thermal shock resistance, and could not cause the glass products loss, result from the glass phase of the products was separated out.
