Abstract
Fluoro- and chloro-substituted perovskites based on barium–calcium niobate Ba2CaNbO5.5 are synthesized. The investigated phases’ capability for hydration is established. It is found that the introduction of a dopant does not change the type of proton-containing particles, and the only forms in which protons occurs are energetically unequal ОН− groups. It is shown that the introduction of a halide ion lowers the degree of hydration, relative to the matrix composition.
