Rare earth element - doped titanium dioxide particles and process for their preparation

摘要

A method for the production of rare earth element - doped titanium dioxide particles, comprising:a step of the production of a liquid precursor comprising a titanium source and a rare earth metal source, wherein the content ratio of said rare earth element in the rare earth metal source in a range of not lower than 0 atom -%, and not higher than 5,0 atom -% is;a step of generating thermal plasma; anda step of introducing the liquid precursor, in the thermal plasma.
