What is ZTA ceramics?

1,ZTA ceramics are zirconia toughened alumina ceramics, which are inorganic non-metallic materials and are very good wear-resistant materials.


2,Zirconia toughened alumina ceramics (ZTA ceramics), which is to add pure Zr02 to the alumina, and the particles form ZrO2 toughened alumina ceramics. When added properly, zirconia can significantly improve the toughness of alumina. It can be said that the toughening of alumina ceramics is currently the most used toughening method. The approximate proportion is to add 20% zirconia (ZrO2) to toughen alumina.


Just because of the high hardness of alumina and the good toughness of zirconia, the two materials became an excellent composite with high strength and high toughness, which is more versatile.


At room temperature, it has higher flexural strength and fracture toughness, so ZTA ceramics have superior wear resistance. The specific ratio of the two materials can be adjusted according to the actual requirements of users.
