Preparation of porous materials from a leucoxene concentrate

摘要

We have studied the effect of leaching conditions on the physicochemical characteristics of titanium dioxide-based powders prepared by leaching a leucoxene concentrate from the Yaregskoe deposit. The results demonstrate that, by varying the leucoxene concentrate leaching conditions and reducing the SiO2 content, one can obtain a porous titanium dioxide-based material with predetermined characteristics: chemical and phase compositions, specific surface area, and others.
