Properties of Zirconia Ceramics

Author:Site Editor     Publish Time: 27-07-2017      Origin:Site

Zirconia ceramics are new ceramics, because zirconia ceramics has a very excellent physical and chemical properties, not only in the field of scientific research has become a hot research, but also in industrial production has also been widely used, it is ceramic materials, high temperature materials and functions Materials, important materials, in a variety of metal oxide ceramic materials, zirconia ceramic high temperature thermal stability and thermal insulation performance is best, suitable for ceramic coating and high temperature parts. The thermal conductivity of zirconia ceramics is the lowest in common ceramic materials, and the coefficient of thermal expansion is close to that of metal materials. It is an important structural ceramic material; zirconia ceramic special crystal structure makes it an important electronic material; good Mechanical properties and thermophysical properties make it as an enhanced phase for excellent performance in the material.

At present in a variety of metal oxide ceramics, the role of zirconia ceramics after alumina ceramics. Phase change toughened zirconia ceramics is a promising new type of structural ceramics, which mainly uses zirconia ceramic phase change characteristics 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 composites and composite ceramics. Over the past decade, zirconia ceramics with various properties and zirconia ceramics for the phase change toughening materials, the rapid development of composite ceramics, in many areas of industry and science and technology has been increasingly widely used. At the same time, the research on the phase transition of zirconia ceramics has been paid more and more attention in the field of solid phase transformation.
