Description

Technical Parameters

Zirconia alumina (ZTA) ceramics

image001_(001)

Zirconia alumina ceramics(ZTA) are zirconia toughened alumina ceramics which are good wear resistant materials. When adding proper zirconia into alumina, the toughness of alumina can be improved significantly.

Application of ZTA

ZTA are widely used in hoppers, rubber belts, pipes, elbows, valves, chute, cyclones, feeders, bunkers, rubber backed composite panel and other equipment of iron, cement, coal, mine, etc.

Parameter index

Item	Data
Bending strength(MPa)	>1000
Fracture toughness (MPam ½)	>7
Rockwell hardness (HRA)	>88
Wear volume(cm³)	<0.1
Density (g/cm³)	>4.2

Characteristic

Zirconia alumina ceramics are made by dry powder after isostatic pressing and then sintering at 1680 degree in tunnel furnaces. The hardness and toughness of ZTA is between alumina ceramic and zirconia ceramic. But its wear resistance and impact resistance is much better than alumina ceramic.

Compared with alumina products, ZTA has higher density, better wear resistance, and stronger toughness. Compared with zirconia products, ZTA has lower price and higher cost performance.
