What is the advantage of ZTA ceramic tile compared to alumina?

Zirconia Toughened Alumina, (ZTA ceramic tile) is often used in wear applications as an intermediate solution between alumina and zirconia.


The main advantage of Zirconia Toughened Alumina (ZTA) is the additional strength and toughness over alumina with a lower cost than zirconia (YTZP, MSZ, CSZ).


The combination of aluminum oxide and 10-20% zirconium oxide provides a much higher strength, toughness, hardness and wear resistance than alumina alone.


The 20-30% increase in strength often provides the design criteria needed at a much lower cost than using zirconia.


A process called transformation toughening is the phenomenon that increases the fracture toughness of ZTA. When placed under stress, the zirconia particles change their crystal structure from a tetragonal to a monoclinic structure, causing a volume expansion that compresses the surrounding crack in the alumina matrix.


ZTA should be considered for any application where structural strength is needed that exceeds the standard alumina properties.


Zirconia Toughened Alumina (ZTA) Ceramic tile and rod has the properties of corrosion resistance and good chemical stability. Alumina has high hardness while zirconia has good toughness. Zirconia Toughened Alumina (ZTA) Ceramic tile has the advantages of both alumina and zirconia and has a wider range of applications in machinery, electronics, petroleum, chemical industry, aerospace, and textile industries. Stanford Advanced Materials (SAM) can adjust the specific ratio of alumina and zirconia in Zirconia Toughened Alumina (ZTA) Ceramic tile according to the actual requirements of users.


Application:Rubber and ZTA ceramic tile composite lining

1.more impact resistant than alumina ceramic: elastic rubber matrix helps absorbing impact energy.

2.more wear resistant than rubber: high alumina ceramic offers excellent wear resistance.

3.steel backing plate with studs or countersunk, easily installation if ceramic-rubber-steel lining.
