Аннотация: Stoichiometric mixtures of Bi₂O₃, Eu₂O₃, and TiO₂ substituted Bi$_{{4 - x}}$Eu_<i>x</i>Ti₃O₁₂ (<i>x</i> = 0.4, 0.8, 1.2, 1.6, and 2.0) titanates are obtained by firing in air at temperatures of 1003–1323 K. Their crystal structure is determined via X-ray diffraction. Their high-temperature heat capacity is measured by means of differential scanning calorimetry. Thermodynamic properties of the titanates are calculated according to experimental data on <i>C</i>_<i>p</i><i>= f</i>(<i>T</i>).
