Introduce the properties of zirconia ceramics

Introduce the properties of zirconia ceramics

Performance of zirconia ceramics: pure ZrO2 is white, yellow or gray when it contains impurities, and generally contains HfO2.

Zirconia ceramics are a new type of ceramics. Because of their excellent physical and chemical properties, zirconia ceramics have not only become a research hotspot in the field of scientific research, but also have been widely used in industrial production.

Zirconia ceramics have the best high-temperature thermal stability and thermal insulation performance, and are suitable for ceramic coatings and high-temperature parts. The thermal conductivity of zirconia ceramics is the lowest among common ceramic materials, and the thermal expansion coefficient is relatively close to metal materials. It is an important structural ceramic material.

At present, among various metal oxide ceramics, the role of zirconia ceramics is second only to alumina ceramics. Phase transformation toughened zirconia ceramics are a promising new type of structural ceramics.

It mainly uses the phase change characteristics of zirconia ceramics to improve the fracture toughness and flexural strength of ceramic materials, so that it has excellent mechanical properties, low thermal conductivity and good thermal shock resistance.

Zirconia ceramics can also be used to significantly improve the toughness and strength of brittle materials, and are important toughening agents in composite materials and composite ceramics.

In the past ten years, zirconia ceramics with various properties and composite ceramics with zirconia ceramics as phase transformation toughening materials have developed rapidly and have been widely used in many fields of industry and science and technology.

At the same time, the research on the phase transition of zirconia ceramics has also received widespread attention from the academic circles, occupying an important position second only to metals in the field of solid-state phase transition research.

The above is the performance of zirconia ceramics brought to you by Pintejin Ceramics.
