Zirconia Toughened Alumina (ZTA)
The main advantage of Zirconia Toughened Alumina (ZTA ceramic tile) is the additional strength and toughness over alumina with a lower cost than zirconia .
The combination of aluminum oxide and 10-20% zirconium oxide provides a much higher strength, toughness, hardness and wear resistance than alumina alone.
ZTA should be considered for any application where structural strength is needed that exceeds the standard alumina properties. American Made. American Owned. ZTA does provide a higher strength than alumina but the temperature limitation of 1500 C (2732 F) must be observed. Above this temperature the strength contribution of the zirconia is reduced.
The 20-30% increase in strength often provides the design criteria needed at a much lower cost than using zirconia.
ZTA should be considered for any application where structural strength is needed that exceeds the standard alumina properties.
Characteristic of ZTA ceramic tile:
Increased Fracture Toughness
The high fracture toughness gives it very good edge strength and makes the material ideal for components subjected to impact loading.
Excellent Wear Resistance
During the sintering process, an extremely smooth microstructure is achieved which leads to superior wear performance.
Good Thermal Conductivity
ZTA materials provide for good dissipation of heat generated by friction.
