Application range:
1. Battery Additives: Stabilizing
nano-zirconia as an ideal electrolyte has been widely used in solid oxide fuel
cells.
2. Functional ceramics, structural
ceramics: electronic ceramics, bioceramics, sensor ceramics, magnetic
materials, etc.; nano-zirconia improves the toughness, surface finish and
ceramic density of ceramic structural parts.
3. Spray coating, piezoelectric element,
oxygen sensitive resistor, large capacity capacitor.
4. Artificial gemstones, abrasive
materials, polishing materials. Functional coating materials: added to the
coating to have anti-corrosion, anti-bacterial effect, improve wear resistance.
5. Nano-zirconia is used for refractory
materials: electronic ceramic burning support pad, fused glass, metallurgical
metal refractory.
