| Abstract: | A new perovskite-like oxide (Rb2Nd2Ti3O10) is synthesized by the ceramic method. Its stability in a humid atmosphere and aqueous solutions of different acidities is investigated. Under these conditions, the formation of hydrated and protonated compounds is revealed. The parameters of the unit cell of the Rb2Nd2Ti3O10 oxide and its derivatives and the degree of rubidium substitution by protons for the obtained protonated phases are determined. |
