Aluminum oxide ceramics are a type of high-temperature structural ceramics with excellent properties such as high strength, high temperature resistance, and corrosion resistance. However, its brittleness limits its application, and improving the toughness of Al2O3 ceramics has always been a topic of in-depth research by many scholars. ZrO2 toughened Al2O3 ceramics, also known as ZTA ceramics, are considered an effective toughening method.

After several years of effort, people have gained a certain understanding of the mechanical properties, preparation process, internal structure, and toughening mechanism of ZTA nanoceramics, but there are still some issues that need further research. In addition, how to obtain dense nanocrystalline ZTA ceramics is also a question worthy of in-depth exploration. Research has found that adding nano dispersed phases to ceramic matrices greatly improves the strength, toughness, and high-temperature performance of materials. The introduction of nano ZrO2 also greatly improves the mechanical properties of Al2O3.

(Zirconia toughened alumina) ZTA zirconium aluminum composite ceramic lining plate: Compared with alumina products, it has higher density, better wear resistance, and greatly improved toughness; Compared with zirconia products: low price and high cost-effectiveness; Specific gravity: 4.2-4.3g/cm3

Our company's ZTA zirconium aluminum composite lining board has become increasingly mature. According to the customer's requirements for performance, we mainly add two types of zirconia content, 20% zirconia and 25% zirconia.
