ATZ (ZrO₂ + 20% Al₂O₃) :

ATZ (Alumina Toughened Zirconia) is a composite ceramic consisting of small alumina particles dispersed in a Y-TZP matrix (zirconia doped with 3mol% Y₂O₃).It is unique  in combining and further improving many of the best properties of the individual materials. ATZ is often specified for the most demanding applications that require high strength, hardness, excellent fracture toughness, and wear and corrosion resistance.

Characteristics :

The main properties are :

• Hardness
• Wear resistance
• Excellent ageing resistance
• Excellent mechanical strength
• Biocompatibility

Applications :

ATZ is a ceramic widely used in the following applications :

• Medical (orthopedic prostheses, …)

• Industrial field (cutting tools, wear parts, bearings, nozzles, …)

• Fluid management (filling pumps, ball valves, anti-corrosion coating, …)

• Jewellery (white color, available in polished quality)
