1.Product Description

Zirconia Alumina is produced in an electric arc furnace at temperatures in excess of 2700°C. Zirconia is very thermally stable to high temperatures (excellent thermal shock resistance), has low thermal conductivity, and is chemically inert.

3.Usage

  Zirconia is also not wetted by many metals and glasses and is therefore an excellent contact material in the existence of slags. Zirconia can also be combined with alumina to make a tough abrasive grain used in bonded and coated abrasives. Fused Zirconia is used in steel and glass contact refractories, investment casting as shell building material, as wear resistant coatings, thermal barrier coatings, and other applications that require high temperature, wear resistance, and frequent thermal cycling.
