ZTA Rods

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.

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.

1. ZTA ceramic has high toughness and tensile strength, high temperature resistance, good thermal shock resistance, oxidation resistance, corrosion resistance and wear resistance, and can maintain stable performance under harsh working conditions.

 

2. ZTA ceramic has excellent electrical insulation properties and high breakdown voltage resistance.

 

3. ZTA ceramic has very good chemical inertia and biological compatibility, and do not react with various chemical media and medical reagents, non-toxic and harmless.

 

4. ZTA ceramic has low density and light weight, which can effectively reduce the weight and load of the equipment.
