摘要: A method for producing fine particles of metal oxide characterized in that metal halide is hydrolyzed in the presence of organic solvent. According to this invention, under hydrolysis of titanium tetrachrolide, anatase type titanium oxide can be obtained by selecting hydrophilic organic solvent, and rutile type titanium oxide can be obtained by selecting hydrophobic organic solvent.
