Product Description
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 coatings.
The unique low thermal conductivity of nano zirconia is an excellent material for thermal insulation coatings to improve the thermal insulation effect. Its high corrosion resistance, high hardness, and high wear resistance are also good materials for coating modification. Nano zirconia is used in thermal barrier coatings Grade zirconia VK-R30, the mechanical, electrical, thermal, anti-friction, anti-wear and anti-corrosion properties have been greatly improved. Experiments have proved that after adding 2% of VK-R30, the bonding strength of thermal barrier coatings can reach 100Mpa.
Nano-zirconia has special optical properties, and its reflectivity to ultraviolet long-wave, medium-wave and infrared rays is as high as 85%. After the coating is dried, the nanoparticles tightly fill the gaps between the coatings to form a complete air insulation layer, and its own low thermal conductivity can force the heat transfer time in the coating to be longer, making the coating also have a lower thermal conductivity. The thermal conductivity can improve the thermal insulation performance of the coating.
Application
1. Nano-zirconia can be used in high-strength, high-toughness wear-resistant products: mill linings, wire drawing dies, hot extrusion dies, nozzles, valves, balls, pump parts, various sliding parts, etc.
2. Functional ceramics, structural ceramics: electronic ceramics, bioceramics, sensor ceramics, magnetic materials, etc.;
3. Piezoelectric elements. Oxygen sensitive resistors. Large capacity capacitors;
4. Artificial gemstones, abrasive materials, and functional coating materials: added to coatings to have anti-corrosion and anti-bacterial effects, and improve wear-resistant and fire-resistant effects.
5. Nano zirconia can also be used as refractory materials: electronic ceramics firing support plates, melting glass, refractory materials for metallurgical metals;
The application in the high-tech field is expanding day by day.
6. The toughness and strength of ceramic structural parts added with nano-zirconia are significantly improved, not only the surface finish is good, but also the ceramics are dense and resistant to falling.
7. Thermal insulation coating, high temperature resistant coating.
