Abstract

TiO2 in powder form was preferred due to its flexibility and easy handling. TiO2 powders with controlled crystal phase were successfully synthesised by ultrasonic spray pyrolysis from titanium tetraisopropoxide (TTIP) precursor. The effect of various acid solvents (nitric acid, acetic acid and citric acid) in relationship with crystal compositions have been well-studied. This experimental study suggested that the ratio of anatase phase achieved from TiO2 prepared by nitric, acid acetic acid and citric acid solvent are 85%, 39% and 27% respectively. Spurs-Myers equation used to determine the anatase-rutile phase. Crystal sizes were calculated using Scherer equation. Both of ratio and crystal size were estimated from corresponding X-ray diffraction pattern. Precipitation and chelating process were the keys to determine the last composition of TiO2.
