Zirconia Toughened Alumina (ZTA) Ceramic

Zirconia toughened alumina (ZTA) ceramic is a common advanced industrial ceramics, with oxidized powder as the main raw material, adding a certain proportion of zirconia powder as a toughening agent, through forming and high temperature sintering process. Compared with alumina, ZTA keeps high hardness, high temperature resistance and corrosion properties, while toughness and tensile strength has been greatly improved. It has important applications in various mechanical equipment, high temperature fire resistance, petrochemical industry, compared with zirconia the material density is small, with light weight, also the cost is lower.

Q：What is the maximum operating temperature for Alumina Ceramic?What are the mechanical strength benefits of Zirconia Toughened Alumina (ZTA) Ceramic compared to standard Alumina?

A：ZTA Ceramic offers enhanced mechanical strength and toughness compared to standard Alumina due to the incorporation of Zirconia, which increases resistance to cracking and improves durability in high-stress applications.

Q：How does ZTA Ceramic perform in high-temperature environments?

A：ZTA Ceramic can operate effectively at high temperatures, similar to pure Alumina, with an operating range up to approximately 1600℃. The zirconia content provides additional stability and resistance to thermal degradation.

Q：What are the wear resistance properties of ZTA Ceramic?

A：ZTA Ceramic has superior wear resistance compared to standard Alumina due to its higher hardness and toughness, making it suitable for applications where high abrasion resistance is required, such as in cutting tools and wear parts.

Q：Is ZTA Ceramic resistant to chemical corrosion?

A：ZTA Ceramic maintains good chemical corrosion resistance, similar to Alumina, and is resistant to most acids, alkalis, and solvents, making it suitable for use in chemically harsh environments.

Q：Can ZTA Ceramic be used in biomedical applications?

A：Yes, ZTA Ceramic is biocompatible and is often used in biomedical applications such as orthopedic implants and dental restorations, where its combination of toughness and wear resistance is particularly valuable.

Properties of Zirconia Toughened Alumina (ZTA) Ceramics

ZTA ceramic has very comprehensive performance, it combines property of alumina and zirconia ceramics, toughness is much higher than alumina, while density and cost is lower than zirconia.
