Zirconium Aluminium Oxide

Zirconium Aluminium Oxide, also Zirconia Toughened Alumina or ZTA in short, is a common product for the abrasive industry where it is used as one of the major cutting media. It is also used as shot-/sand-blasting media and for engineering ceramics. Zirconium Aluminium Oxide shows significantly improved toughness to the cutting grain compared to alumina grains, improving life. It is largely used in coated abrasives.

The product typically comes in two versions; one with 25% zirconia and another with 40% zirconia content. Various particle size distributions are available.
