In this work, a number of titanium oxide powders with different crystal structures and textural characteristics were synthesized. The initial raw materials were metallic titanium and rutile (rutile particle size 25 ?m, specific surface area 3 m2/g), from which titanium salts were synthesized with their subsequent decomposition. Titanium salts were obtained by interaction with mineral acids and ammonium carbonate. The resulting salts were thermally decomposed or hydrolyzed by adding ammonium hydroxide, which led to the precipitation of titanium oxide. The phase composition of the synthesized samples included rutile and anatase, as well as titanium fluoride impurities at low firing temperatures.
A relatively simple and economically feasible method for synthesizing titanium oxide with a specific surface area of up to 92 m2/g by simple chemical transformations is proposed, which involves thermal decomposition of synthesized titanium halides. The best of the synthesized anatase samples had the shape of irregular polyps, a specific surface area of 56…92 m2/g, and a particle size of 20…60 ?m.
