Zirconia Toughened Alumina (ZTA) is a high-performance composite ceramic that combines the hardness of alumina with the superior toughness of zirconia. By integrating 10–20% zirconia into the alumina matrix, ZTA exhibits significantly enhanced flexural strength, fracture toughness, hardness, and wear resistance, often 20–30% stronger than alumina alone.

This improvement is due to transformation toughening, a mechanism where zirconia particles undergo a phase change under stress, helping to stop crack propagation and increase durability.

• Excellent wear and corrosion resistance
• High mechanical strength and hardness
• Enhanced fracture toughness
• Good chemical stability
• Cost-effective alternative to pure zirconia
• Customizable alumina-to-zirconia ratios to meet specific application needs
