Zirconia Toughened Alumina/ZTA Powder (ZTA - Al₂O₃ 90 / ZrO₂ 10)

ZTA powder (Zirconia Toughened Alumina), also known as ZTA - Al2O3 90 / ZrO2 10, is an alumina-zirconia composite powder from Goodfellow's range of ceramic powders. It combines the hardness and wear resistance of alumina with the toughness of zirconia. The 10% zirconia inhibits crack propagation, increasing the fracture toughness. Common applications of ZTA powder include medical devices, ballistic armor, and cutting tools where high hardness, wear resistance, and toughness are required.
