Application

Zirconium(IV) oxide (ZrO2) which is also known as zirconia is a ceramic nanoparticle that can be used as a nano-filler. ZrO2 process yields a consistently high purity zirconia composed of monoclinic phase particles. The low surface area and unique spheroid-shaped particles find applications in ceramics, high-temperature fillers, sensors, and catalysts.
