Hydrothermal synthesis of the sitinakite on the basis of leucoxene of the Yaregskoe deposit

Microporous titanosilicate - sitinakite was synthesized by a method of hydrothermal synthesis in an alkaline condition. As precursors the products of ammonium fluoride processing of the leucoxene of Yaregskoe deposit were used. Influence of concentration of alkali on structure and structure of the synthesized titanosilicate is considered.
