SUOYI Nano Zirconia Magnesium Stabilized for Technology Ceramic Structural

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.

1. Nano zirconium oxide can be used in high strength, high toughness wear-resistant products: mill lining, cutting tools, drawing die, hot extrusion die, nozzle, valve, ball, pump parts, a variety of sliding parts, etc.

2. Functional ceramics, structural ceramics: electronic ceramics, biological ceramics.

3. Piezoelectric elements. Oxygen sensitive resistors. Large capacitors;

4. Artificial gem, abrasive material. Functional coating material: anti-corrosion and anti-bacterial action in coating, improving wear-resisting and fire resistance.

5. Nano-zirconia can also be refractory materials: electronic ceramic burning support plate, melting glass, metallurgical metal refractory materials;

Applications in the field of high technology are expanding.

6. After silane modification of nano-zro2 particles, it can significantly improve the flexural strength of nano-zro2 /PMMA composite materials when its addition amount is 3.0%.
