Abstract

See full text

A method for producing nano-sized titanium dioxide (TiO.sub.2) ultrafine powder from titanium tetrachloride (TiCl.sub.4) in the vapor phase by the gas phase oxidation reaction using flames, in which the method comprises: simultaneously introducing titanium tetrachloride (TiCl.sub.4), vapor, argon, oxygen, hydrogen and air into a five-piped flame reactor to form a flame having a temperature of greater than 1,000.degree. C.; and producing nano-sized titanium dioxide ultrafine powder having an average particle size of less than 50 nm.
