The titanium dioxide nanocrystals have particle diameters of 1-20 nm. The preparing process has the features of mild reaction conditions and is a simpler and easier method with a shorter preparation period, thereby facilitating the industrialization.
The titanium dioxide nanocrystals prepared by the Chinese Academy of Sciences method have small particle diameters, narrow size distribution, and can be dispersed stably in a non-polar solvent. The manufacturing method solves the problem that titanium dioxide nanocrystals are difficult to processing during its application. The whole preparing process of the material has the features of mild reaction conditions and is a simpler and easier method, and has a short preparation period, and is suitable for mass production.
