Zirconia Toughened Alumina Ceramic

Supplier: Ceramic Oxide Fabricators (Australia)

Zirconia Toughened Alumina (ZTA) is high purity alumina mixed with zirconia, making a tougher, stronger material.

Price Guide: POA

Zirconia Toughened Alumina:

  • Combines the advantages of partially stabilised zirconia (PSZ) and of alumina
  • Almost as hard as alumina
  • Almost as strong as PSZ
  • From 3 to 10 times more abrasion resistant than high purity alumina.
