Zirconia Alumina

Zirconia alumina is used for producing abrasives of very high toughness with long life. Produced by cleaning and crushing fused electocast blocks, it has nil porosity, high density and excellent refractoriness. It is generally used as sand blasting medium and as an abrasive in foundry and casting processes.
