POLYMORPHIC TRANSFORMATION OF TITANIUMDIOXIDECAUSED BY HEAT TREATMENT OF PROTONIC LEPIDOCROCITE TITANATE

ABSTRACT The polymorphic phases of titanium dioxide were successfully prepared by heat treatments of protonic lepidocrocite titanate, HO.5T4i1.86sOo.13.0s.054HzOat various temperatures. The prepared powders were characterized with EDX (Energy Dispersive X-ray), Scanning Electron M~croscopy(SEM), X-r...
