Noted: we also have other Nano Powder.
Nano Zirconium Dioxide Powder
Property: Small particle size of 20-40nm, 99.9% purity
Characteristic:
Ceramics have good permeability and high bright cleanliness of surface when you Add 3Y yttria stabilized Nano-zirconia to it.
Applications:
1. The product can be used on high strength, high toughness, wear-resistant products: Mill lining, Cutting tools,
drawing dies, hot extrusion die, nozzles, valves, ball, pump parts, a variety of sliding parts, etc.;
2. The product can be used on functional ceramics, structural ceramics, in particular, electronic ceramics, Biological ceramics (such as: Denture)
3. The product can be used in refractory materials: Electronic ceramic bearing plate burning, melting glass, Metallurgy and metal materials;
4. After si-lane modified, when nano-ZrO2 particles are in the 3.0% addition level,
you can significantly Improve the nano ZrO2/PM MA composite flexural strength.
We also produce 300 tons of 5Y yttria stabilized Nano-zirconia powder and
Particles and 300 tons of 8Y yttria stabilized Nano-zirconia powder and particles per year.
