ZTA ceramics, abbreviated as composite ceramics, also known as zirconia toughened alumina ceramics. ZTA ceramics are wear-resistant, 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; In many situations where alumina ceramics are not competent, it shows better cost-effectiveness than zirconia ceramics. Therefore, ZTA ceramics are widely used in industries such as machinery, electronics, petroleum, chemical, aerospace, and textiles.

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

1. The fineness of zirconia;

2. Zirconia is uniformly dispersed in alumina;

3. There is no abnormal crystal growth during the sintering process.
