Applications of Alumina Zirconia for Refractory
They are suitable for making billet snagging and foundry snagging wheels, coated tools, high-grade zirconium refractory material, etc. They apply for the Iron and steel industry, continuous casting and rolling, nozzle, flow channel, glass furnace refractories, etc. Zirconium Oxide can use for grinding hard metals and materials.
Advantage of Alumina Zirconia for Refractory
- High hardness
- High toughness
- Good particle shape and size
- High Bulk density
- High-temperature resistance
