Аннотация
Solid solutions of composition Ca12-x(Al14Vx)O33+δ (0 ≤ x ≤ 0.07) were synthesized. The V oxidation state in the solid solution was found using a combination of methods. The principle for filling mayenite crystallographic positions with dopant proposed that V cations replace a few Al positions, presumably in octahedral coordination. The temperature dependence of Ca11.93(Al14V0.07)O33+δ electrical conductivity was studied by impedance spectroscopy. The electrical conductivity of V-doped mayenite was shown to increase by an order of magnitude.
