Zirconium Oxide (ZrO2) Nanopowder Main Feature
ZrO₂ nanoparticles have a high surface area to volume ratio, which significantly enhances their reactivity and interaction with other substances. This feature is particularly beneficial in catalysis and surface modification applications.Zirconia nanopowder maintains its structural integrity and chemical properties even at very high temperatures. This thermal stability makes it suitable for use in extreme environments, such as in thermal barrier coatings for gas turbines and jet engines.Nanoscale zirconia exhibits superior mechanical properties, including high strength, toughness, and wear resistance. These characteristics are utilized in the production of advanced ceramics, cutting tools, and wear-resistant coatings. Zirconia undergoes phase transformations that can be manipulated at the nanoscale to achieve desired properties, such as increased toughness. The stabilization of the tetragonal and cubic phases of zirconia at room temperature can be achieved through doping with certain oxides, enhancing its fracture toughness and resistance.
