Abstract

Current TiO2 technologies are complex and costly in terms of reagents and energy. Due to the high sinterability of the titanium dioxide particles, the calcination of the hydrate precursor requires several grinding stages of the product as well as TiO2 particles surface modification to improve performance, including oil capacity. A solid-phase proccess for the production of anatase titanium dioxide has been developed based on the thermolysis of a crystalline titanium (IV) salt, a semi-product of sulfuric acid processing of sphene concentrate.
