Nano zirconia ceramics

Nano-zirconia is a white solid, with a molecular weight of about 123.22, a boiling point of about 4275 degrees Celsius, a relatively high hardness, an insulator at room temperature, and excellent electrical conductivity at high temperature. One of the products that is widely used in all countries of the world. Its high temperature resistance and high wear resistance and stable chemical properties occupy a great advantage in the CNC industry. The zirconia ceramic material usually needs to be cut, ground, ground and polished to make the required parts. This process requires mechanical processing, and zirconia ceramic processing properties include cutting, grinding, grinding and polishing.

The properties of nano zirconia:

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, Sio2) 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.). Utilizing the conductive properties of nano-zirconia doped with different elements for electrode fabrication in high-performance solid-state batteries.

Ceramics sintered from nano-zirconia powders have become one of the main structural ceramics due to their good properties of phase transformation and toughening; Remarkable effect; stabilized nano-zirconia as an ideal electrolyte has been widely used in solid oxide fuel cells.

Application range:

Nano-zirconia powder has important application value in high-tech fields such as national defense, electronics, high-temperature structure and functional ceramics, especially in surface coating.

1. 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.

2. Functional ceramics (ceramic buttons, ceramic chopsticks), structural ceramics: electronic ceramics, bioceramics;

3. Piezoelectric components, oxygen sensitive resistors, large-capacity capacitors;

4. Artificial gemstones, abrasive materials, and functional coating materials: adding coatings has anti-corrosion, anti-bacterial effects, and improves wear-resistant and fire-resistant effects.

5. Nano-zirconia can also be used as refractory materials: electronic ceramic burning support pads, molten glass, metallurgical metal refractories; applications in high-tech fields are expanding.

6. When the addition amount of silane-modified nano-ZrO particles is 3.0%, the flexural strength of nano-ZrO/PMMA composites can be significantly improved.
