超细氧化锆

zirconium dioxide

essential information:

CAS#：1314-23-4             

nature:

Nano zirconia is a white solid with a molecular weight of 123.22, a melting point of 2397 ℃ and a boiling point of 4275 ℃. It has high hardness and is an insulator at room temperature, while exhibiting excellent conductivity at high temperatures

Nano zirconia has the characteristics of strong thermal shock resistance, high temperature resistance, good chemical stability, and outstanding material composites. Composite of nano zirconia with other materials (Al2O3, SiO2) can greatly improve the performance parameters of the material, enhance its fracture toughness, bending strength, etc. Therefore, nano zirconia is not only applied in the fields of structural ceramics and functional ceramics, but also in improving the surface properties of metal materials (thermal conductivity, thermal shock resistance, high-temperature oxidation resistance, etc.). Utilizing the conductive properties of different elements doped with nano zirconia for electrode manufacturing in high-performance solid state batteries.

Ceramics sintered from nano zirconia powder have become one of the main structural ceramics due to their excellent performance in phase transformation and toughening; In the research of nanocomposites, significant effects have been achieved by using nano zirconia as a dispersed relative matrix for strengthening and toughening; Stable nano zirconia has been widely used as an ideal electrolyte in solid oxide fuel cells.
