Amorphous titanium hydroxide with spherical shape was obtained from precipitation from homogeneous solution (PFHS) method using titanyl sulfate and urea as precipitant. Two stages of weight loss for the as-prepared particles were measured on heating process in air. First stage at lower temperature and second stage at higher temperature of weight loss correspond to the dissociation of hydrate and sulfate radical respectively. In particular, crystallization of as-prepared particles to anataze type titanium(IV) oxide proceed noticiably at about 600°C on heating. Existence of sulfate radical may play a role in stabilization of the amorphous state for titanium (IV) hydroxide.
