Abstract

The invention discloses a zirconia composite nano-powder material and a preparation method thereof and belongs to the field of manufacturing for metal oxide ultra-microstructures. The zirconia composite nano-powder material is characterized by being composed of the following chemical constituents in percentage by mass: 70-90% of zirconium dioxide ZrO2 and 10-30% of titanium dioxide TiO. The preparation method comprises the following steps: continuously spraying atomized ammonium bicarbonate aqueous solution in the absolute ethyl alcohol solution of zirconium oxychloride ZrOCl2.8H2O and butyl titanate which are pre-prepared respectively and uniformly mixed, while stirring, to react to prepare a mixed sol, using butanol as an azeotropy agent for the mixed sol, and then calcining the dry material after butanol azeotropy and dehydration to prepare the zirconia composite nano-powder material; the zirconia composite nano-powder material has a particle size of 30-50 nm and a specific surface area of not less than 30 m<2> / g. A zirconia composite nano-powder material which is high in activity, and good in dispersity and stability is provided; the zirconia composite nano-powder material is suitable for heat-isolating coatings for building outer walls, transparent heat-isolating coatings for vehicle windows and building glass, and transparent heat-isolating conductive coatings, as well as also suitable for being used for preparing catalysts and catalyst carriers, and used as biological materials for dentistry and orthopaedics.

Description

technical field [0001] The invention relates to a zirconia composite nano powder material and a preparation method thereof. It belongs to the manufacture of metal oxide ultramicrostructure. Background technique [0002] Nanoparticles are aggregates composed of a small number of molecules or atoms. They are between macroscopic substances and microscopic atoms and molecules. They have high activity and are in a thermodynamically unstable state. [0003] Nanopowder materials refer to powders or particles with a particle size of 1-100nm. Due to its small particle size, large specific surface area and many interfaces, it exhibits many special physical and chemical properties different from conventional powders, namely surface effect, small size effect, quantum size effect, macroscopic quantum tunneling effect, etc. It is precisely because of these special properties of nanoparticles that endow nanoparticles with excellent properties that many macroscopic materials cannot match....
