The molecular formula of Nanometer zirconium dioxide is ZrO2, melting point is 2680 ℃ and boiling point is 4300 ℃.
Nanometer Zirconium Dioxide refers to that the particle size is nanometer level of ultrafine grain. The grain size of zirconia nanoparticles is larger than the atomic clusters, less than the usual powder, generally the boundaries between 1 ~ 100 nm. Most of the zirconia nanoparticles is the ideal single crystal, and minority is amorphous and semi-stable state. When the small particle size become the nanometer level, its and itself composed of nanometer solid have quantum effect, small size effect, surface effect and macroscopic quantum tunneling effect, etc. And thus zirconium oxide nanoparticles derived many special properties which the traditional solid does not have, zirconium oxide nanoparticles has broad application prospects in catalyst promoter, light filtering, light absorption, medicine, magnetic medium and new materials.

Nanometer zirconium dioxide fiber is a kind of polycrystalline refractory fiber material. Due to ZrO2 material itself has the high melting point, no oxidation and other high temperature excellent properties, ZrO2 fiber is better than the alumina fiber, mullite fiber, aluminum silicate fiber, and other varieties of refractory fiber. Zirconia fibers can use for a long time above 1500℃ ultra high temperature oxidation atmosphere, the highest temperature as high as 2200 ℃, and even to 2500 ℃ can still intact fiber shape. With high temperature and chemical stability, corrosion resistance, oxidation resistance, thermal shock, non-volatile, no pollution, ultrafine Zirconia Powder is the top refractory fiber material in international. The resisting to acid and alkali, corrosion resistance ability of ZrO2 are greatly stronger than SiO2 and Al2O3.Adding nanometer zirconium oxide can effectively improve thermal shock resistance of refractory products.
2.The toughening agent and anti cracking agent for ceramic materials
Add 10% content of nanometer zirconium dioxide in ordinary zirconia ceramics, can effectively prevent the ceramic craze and toughen ceramic, so that ceramic sintering temperature is reduced, increase strength, resistance to break and durable.
Nanometer zirconia (ZrO2) has high temperature resistance, chemical corrosion resistance, oxidation resistance, wear resistance, big thermal expansion coefficient, small heat capacity and thermal conductivity, thus it is determined an ideal heat preservation material. Zirconium oxide nanoparticles has high hardness good abrasion resistance, widely used in wear-resistant coatings.
Nanometer zirconium oxide as the only one metal oxide which with acid, alkali, oxidizing and reducing. Its unique characteristics and properties of the zirconia nanoparticles have very important scientific research value and application prospect in catalyst promoter. In recent years, the studies of catalyst promoter are very much, and some research results of catalyst promoter have been applied in industrial practice
