Alumina ceramics have received widespread attention because of their high melting point, high hardness, excellent high temperature stability and low price. However, due to their low toughness, it is always easy to cause ceramic materials to be used in industrial, medical and living fields. The threatened destruction greatly limits the application of alumina ceramics.

When introducing zirconia into alumina ceramics, zirconia toughened alumina (ZTA) ceramics can be prepared. Zirconia can play the role of phase change toughening and microcrack toughening in alumina ceramics, toughening and strengthening alumina ceramics, thereby improving the toughness of alumina ceramics, so ZTA ceramic tiles are very promising ceramic materials .
