As the professional manufacture, we would like to provide you Nextgen Zirconia Toughened Alumina Ceramic Sheet and Plate. Nextgen Advanced Materials INC prides itself in serving these markets with a focus on satisfying individual client’s needs and requirements. 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.ZTA should be considered for any application where structural strength is needed that exceeds the standard alumina properties.
