General description

Zirconium oxide (ZrO2) is a white powder characterized by its monoclinic crystal structure and a particle size of less than 10 microns. This material appears as a white powder and is known for its high stability and resistance to corrosion. Zirconium oxide combines excellent mechanical properties with thermal stability, making it suitable for a wide range of applications, including ceramics, thermal barrier coatings, and dental materials. Its unique properties enable its use in environments requiring durability and high performance.

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.
