Abstract
The possibility of forming hollandite-type phases during the solid-phase reaction in the Cs2O(MeO)–Al2O3–TiO2 (Me = Ba, Sr) systems is studied. It is revealed that, in the Cs2O–BaO–Al2O3–TiO2 system, the region of existence of Cs x Ba1 – x/2Al2Ti5O14 solid solutions with a hollandite-type structure lies in the concentration range 0 ≤ x ≤ 0.7. In the SrO–BaO–Al2O3–TiO2 system, no solid solutions with a hollandite-type structure are observed. The mechanism and kinetics of formation of the Cs x Ba1 – x/2Al2Ti5O14 (0 ≤ x ≤ 0.7) solid solutions are analyzed, and the optimum conditions for synthesis of these solutions are determined.
