Zirconium Oxide Nanoparticles – Properties, Applications

Nanotechnology has advanced leaps and bounds in the recent past. Applications of nanoparticles have entered into a variety of fields such as electronics, cosmetics, medicine and bio technology. This article will look into the properties and applications of zirconium oxide nanoparticles.

Zirconium oxide nanoparticles (ZrO2) are available in the form of nanodots, nanofluids and nanocrystals having a white surface area. They are often doped with yttrium oxide, calcia or magnesia. Zirconium is a Block D, Period 5 element and oxygen is a Block P, Period 2 element. Zirconium oxide is also known as zirconia, zirconium, zircosol and zirconic anhydride.
