ZTA1879 Zirconia Toughened Alumina (ZTA) Ceramic Sheet/Plate Description

Description of ZTA Sheet/Plate

Zirconia Toughened Alumina Ceramics (ZTA composite ceramics) possess notable characteristics such as whiteness, corrosion resistance, and excellent chemical stability. Alumina provides high hardness, while zirconia contributes to good toughness. The combination of these materials forms a superior composite with high strength and toughness, enabling a wide range of applications.

ZTA ceramics exhibit higher flexural strength and fracture toughness at normal temperatures, resulting in outstanding wear resistance. The ratio of alumina to zirconia can be adjusted to meet specific user requirements. Zirconia toughened alumina ceramics outperform 99% alumina ceramics in terms of performance while being more cost-effective compared to pure zirconia ceramics.

This makes ZTA ceramics an excellent choice when alumina ceramics are not suitable for a given application, offering improved cost performance and maintaining desirable mechanical properties.
