Zirconia Toughened Alumina Powder (Al₂O₃90/ZrO₂10)

Zirconia Toughened Alumina Powder (Al₂O₃ 90/ZrO₂ 10) combines alumina’s inherent hardness and wear resistance with 10% zirconia to enhance fracture toughness and thermal shock resistance. Compared to higher zirconia formulations, this composition prioritizes hardness and stability while still achieving transformation toughening effects. Industries including cutting tools, biomedical implants, and electronics employ ZTA powders for applications requiring durability under stress and resistance to crack propagation. Specific applications include dental restorations, high-strength substrates, and wear-resistant mechanical seals. In research, Al₂O₃ 90/ZrO₂ 10 powders are studied for phase transformation kinetics, aging behavior, and microstructural tailoring. Their optimized balance of hardness, toughness, and chemical stability ensures utility in both structural and biomedical innovations.
