Introduction
Nanometer zirconia sintered powder has the characteristics of strong thermal shock resistance, high temperature resistance, good chemical stability, outstanding composite performance of the material, combining it with other materials (Al₂O3, SiO₂), can greatly improve the performance parameters of the material, and enhance the fracture toughness and bending strength of the material.
Therefore, it is not only used in structural ceramics, functional ceramics and other fields, but also can be used to improve the surface properties of metal materials (thermal conductivity, thermal shock resistance, high temperature oxidation resistance, etc.), using the conductive properties of doped different elements of nano zirconia to manufacture high-performance solid state battery electrodes.
In the study of nano-composites, remarkable results have been obtained by using nano-zirconia as dispersed relative matrix to strengthen and toughen them.
Specific Application
1. can be used for high strength, high toughness wear-resistant products, such as abrasive lining, cutting tools, drawing dies, hot extrusion dies, nozzles, valves, balls, pump parts and various sliding parts.
2. Functional ceramics (ceramic buttons, ceramic chopsticks), structural ceramics: electronic ceramics, biological ceramics
3. Piezoelectric components, oxygen resistors, large capacity capacitors;
4. Functional coating material: added to the coating has anti-corrosion, anti-bacterial effects, improve wear resistance and fire resistance.
5. Refractory materials for electronic ceramic firing support pads, molten glass and metallurgical metals;
The application in the high-tech field is expanding day by day.
Silane-modified nano-ZRO ₂ particles can significantly improve the bending strength of nano-ZRO ₂/PMMA composites when the addition amount is 3.0%. e resistors, and large capacity capacitors;
