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...

description 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-rays Diffractometer (XRD), Raman Spectroscopy, and High Resolution Transmission Electron Microscopy (HRTEM). The effect of calcination temperature on the phase structure and morphology of the heated samples was investigated. The research indicated that the protonic titanate, Ho.54Ti1.86sOo.13504'0.5(0Hz=Ovacancy), lost the inter/ayer water by being heated up to 200°C toproducea dehydratedphase,HO.54Th~o. 13S04.Above 300°C, the dehydrated phase, Ho.54Ti1.86500.1350", completely transformed to TiOz(B)and anatase was obtained as pure phase at 600°C. The phase transformed as the following process: HO.54Th86s00. 13504'0. 5HzO -+ HO.54Ti1. 86sOo.13504'0.25Hz -+ HO.54Ti1.86s00.13S04-+ TiOz(B) -+ TiO
