Product description:
As the most important material in advanced ceramics, zirconia ceramic material is a very important basic material for the development of modern high-tech industry. Zirconia is widely used and has a broad market. The specific applications include solid fuel batteries, automobile exhaust treatment, dental materials, ceramic cutting tools, and zirconia ceramic optical fiber inserts. Zirconia ceramics have high hardness, high wear resistance, good high temperature thermal stability and thermal shock resistance. With the development of zirconia ceramics, its application field has expanded from the field of refractory materials in the past to the field of structural ceramics, bioceramics and electronic functional ceramics. It also has active applications in high-tech fields such as aerospace and nuclear industry. ZrO2 porous ceramics not only have the characteristics of high melting point, high hardness, low thermal conductivity, good thermal stability and small high temperature creep, but also have the characteristics of low density, high strength, high porosity, large specific surface area, strong self-interference to fluid and good filtration and adsorption. In addition, the martensitic transformation of ZrO2 can play a toughening effect of phase transformation toughening, microcrack toughening and dispersion toughening, which can greatly improve the toughness and strength of porous ceramics.
