Thermal transformations of hydrous titanium dioxide

During heating hydrous titanium dioxide with a general empirical formula TiO2·xH2O·ySO3 prepared by hydrolysis of titanium sulphate solution drying, dehydration, desulphurization and anatase — rutile transformation proceed. The studies applying the DTA, TG, DTG methods have been carried out. To separate the particular effects damp samples, dried up to constant mass samples as well as samples after removing sulphur compounds have been used.
