ZTA ceramic abrasion resistant tile linings definition

ZTA ceramic is zirconia toughened alumina ceramics, inorganic non-metallic materials, is a good abrasion resistant tile linings .

Zirconia toughened alumina ceramic linings is ZTA, which is in the 99 alumina by adding pure ZrO2 zirconium oxide particles formed ZrO2 toughened alumina ceramic. When zirconia is added as appropriate, the alumina toughness can be significantly increased. It can be said that the toughening of alumina ceramics is currently the most toughening method, probably add 20% of the ratio of zirconia (ZrO2) can be toughened alumina.

 ZTA's toughening effect mainly comes from the following mechanism:

(1) Alumina crystal grain refinement.

(2) Zirconia phase transformation toughening.

(3) microcracking toughening.

(4) crack turning and bifurcation. ZrO2 toughened alumina ceramics mechanical properties: ZTA (zirconia toughened alumina) ceramic density ≥4.1, Rockwell hardness ≥ 90, Vickers hardness ≥ 1300, fracture toughness 6.0, 480MPa flexural strength, compressive strength of 3600MPa;

ZTA toughened alumina ceramics is based on the addition of alumina to a certain degree of zirconia ceramic ingredients, wear resistance and toughness between the alumina ceramic and zirconia ceramics, because the higher price of zirconia ceramics, the user once Sexual investment is relatively large, the production of the most used manufacturers are mainly European and American companies and BHP Billiton and other groups.
