Method for producing nanometer-sized ultrafine titanium dioxide |
摘要 |
A method for producing nano-sized titanium dioxide (TiO2) ultrafine powder from titanium tetrachloride (TiCl4) in the vapor phase by the gas phase oxidation reaction using flames, in which the method comprises: simultaneously introducing titanium tetrachloride (TiCl4), vapor, argon, oxygen, hydrogen and air into a five-piped flame reactor to form a flame having a temperature of greater than 1,000° C.; and producing nano-sized titanium dioxide ultrafine powder having an average particle size of less than 50 nm.
