Zirconia (ZrO2) nano particle "Zirconeo"

ITEC's zirconia nano particle "Zirconeo" is synthesized by supercritical hydrothermal method.
We provide the Zirconeo powder and Zirconeo dispersion.
Zirconeo is available for high refractive index materials.

Zirconeo nano powder Zirconeo dispersion
·Primary particle diameter is <10 nm.
·Dominant crystal structure of Zirconeo powder is tetragonal.
·We also have yttria stabilized ZrO2.
 ·Primary particle diameter is <10 nm.
·The dispersion is transparent.
·High compatibility with UV resin.
