The key points when making ZTA ceramic

ZTA ceramic is abbreviated as composite ceramics, also known as zirconia toughened alumina ceramics. ZTA ceramics are white, corrosion-resistant, and chemically stable.


The performance of ZTA aluminum ceramics is better than that of 99 alumina ceramics, and the price is much lower than that of zirconia ceramics; many occasions where alumina ceramics are not competent, show a better cost performance than zirconia ceramics. Therefore, ZTA ceramics are widely used in machinery, electronics, petroleum, chemical, aerospace and textile industries.


However, the following key points need to be paid attention to when preparing ZTA ceramics by mixing alumina and zirconia:

1. The fineness of zirconia;

2. Zirconia is uniformly dispersed in alumina;

3. No abnormal crystal growth during sintering.
