Description

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.
