Abstract

The invention discloses a preparation method of nano zirconia hollow spheres, which adopts the reverse precipitation technology, and first prepares a homogeneous solution by using water-soluble zirconium salt, water-soluble yttrium salt solution and deionized water, and then the homogeneous solution is slowly Titration is added to an alkaline solvent containing a complexing agent to prepare a precursor suspension. By adding a mineralizer for hydrothermal reaction, nano-zirconia powder materials and nano-zirconia hollow spheres are synthesized at one time, which greatly shortens the production process. The production cycle saves production and manufacturing costs, and the size of the obtained nano-zirconia hollow spheres is micron-scale, and its particle size is uniform. In addition, the nano-zirconia particles that make up the hollow spheres have the characteristics of high purity, high tetragonal phase, and high dispersion.

Description

technical field

[0001] The invention relates to the technical field of inorganic non-metallic powder materials, in particular to a method for preparing nano zirconia hollow spheres by hydrothermal reaction. Background technique

[0002] Due to its extremely small particle size (1-100nm), nanomaterials have surface effects, small size effects, quantum tunneling effects, and quantum size effects. The super large specific surface area and high surface energy make it significantly improve the optical, electrical, magnetic and mechanical properties of the material. In recent years, with the improvement of nano-powder preparation technology, nano-halogen oxide (ZrO 2 ) have been widely used in many fields. Nano-ZrO 2 It has excellent characteristics such as high melting point, high hardness phase change toughening, oxidation resistance, acid and alkali resistance, suitable for catalysis and used as a catalyst carrier, and is an ideal functional structural material.
