Technical Description of zirconium oxide powder

1. The product has high purity, small particle size, uniform distribution, large specific surface area, high surface activity, low bulk density, and is prepared by gas phase method, which overcomes the disadvantages of hard agglomeration, difficult dispersion and low purity of particles prepared by wet chemical method on the market. ;

2. Nano zirconium dioxide is a white powder with a molecular weight of 123.22, a melting point of 2680°C, a boiling point of 4275°C, high hardness, an insulator at room temperature, and excellent electrical conductivity at high temperature;

3. Nano zirconia has the characteristics of strong thermal shock resistance, high temperature resistance, good chemical stability, and outstanding material composite properties. Combining nano-zirconia with other materials (Al2O3, Y2O3) can greatly improve the performance parameters of the material, improve its fracture toughness, flexural strength, etc. Therefore, nano-zirconia is not only used in the field 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.). Utilize the conductive properties of nano-zirconia doped with different elements for electrode fabrication in high-performance solid-state batteries;

4. Ceramics sintered from nano-zirconia powder have become one of the main structural ceramics due to their good performance of phase transformation and toughening; in the research of nano-composite materials, nano-zirconia is used as a dispersed relative matrix to strengthen and toughen, Good results have been achieved; stabilized nano-zirconia has been used in solid oxide fuel cells as an ideal electrolyte;

5. Nano-zirconia has small particle size, strong stability, and has the properties of acid resistance, alkali resistance, corrosion resistance and high temperature resistance. It can be used in functional ceramics and structural ceramics, as well as gem materials. Its performance is greatly improved than that of micron zirconia.

Application field of zirconium oxide powder

1. Nano-zirconia is used in structural ceramics, functional ceramics, nano-catalysts, solid fuel cell materials, functional coating materials, refractory materials, and other chemical, metallurgy, ceramics, petroleum, machinery, aerospace and other industrial fields;

2. Nano zirconia can be used in high-strength, high-toughness wear-resistant products: mill linings, cutting tools, wire drawing dies, hot extrusion dies, nozzles, valves, balls, pump parts, various sliding parts, etc.;

3. High-purity zirconia can be used as enamel enamel, refractory and electrical insulating material due to its high refractive index and high temperature resistance;

4. High-purity zirconia can also be used in refractory crucibles, X-ray photography, grinding materials, and together with yttrium to manufacture light sources in infrared spectrometers;

5. Artificial gemstones, abrasive materials. Functional coating materials: anti-corrosion and anti-bacterial effects are added to the coating to improve wear-resistant and fire-resistant effects;

6. Nano-zirconia can also be used as refractory materials: electronic ceramic burning support pads, refractory materials for melting glass and metallurgical metals;

The application in high-tech fields is expanding day by day;

7. When the addition amount of silane-modified nano-ZrO2 particles is 2.0%, the flexural strength of nano-ZrO2/PMMA composites can be improved.
