Abstract
A process for titanium dioxide of rutile modification preparation comprises thermal hydrolysis of titanium tetrachloride solution in the presence of titanium nuclei and compounds of trivalent titanium, separation of a precipitate being formed and thermal treatment thereof. In order to increase purity of senseless product by admixtures of sulphatechloride and hydroxide anions and obtaining of particles having spherical shape and specific surface of 1-3 m2/g, the hydrolysis is carried out at acid factor, equal to 1.4-1.6. Titanium hydroxide of rutile modification TiO2 is used as titanium nuclei.
