Process of Production and application :
Fused Alumina-Zirconia is produced in a high temperature electrical arc furnace by fusing zirconium quartz sand and alumina. It is characterized by hard dense structure, high toughness, good thermal stability. It’s suitable for manufacturing large grinding wheels for steel conditioning and foundry snagging, coated tools and stone blasting, etc.
It is also used as an additive in Continuous casting refractories. Due to its high toughness it is used to provide Mechanical strength in these refractories
