Titanosilicates of Kola Alkiline province as a prototypes of various functional materials
The main structural features of the titanosilicate minerals from intrusions of the Kola alkaline province - prototypes of various functional materials used as sorbents, molecular sieves, ion exchangers, precursors for tanning agents, non-linear optical materials and photocatalysts (lintisite-kukisvumite group, murmanite group, kamenevite, ivanyukite group, sitinakite, zorite group, natisite, labuntsovite group) are considered. The ion-exchange and sorption properties of titanosilicates determine their using for liquid radioactive waste purification with reliable fixation of radionuclides in the corresponding matrices and their subsequent conversion to synroc-type ceramics. The perspective ion-exchangers seidite and tiettaite are considered.
