Fused Zirconia Alumina

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 and 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.
