Hydrous titanium dioxide fibers were obtained when K2Ti4O9 fibers prepared byKDC method were conduced in deionized water and then treated with acid solution.The phase transition was studied by TG-DTA and XRD. It is showed that hydrous titanium dioxide fibers had a series of phase changes with the increase of the temperature: H2Ti4O9·1.2H2O→H2Ti8O17→TiO2(B)→middle phase→ anatase→ rutile and the formation mechanism was discussed.
