“…The Department of Physical Chemistry and Refractory Oxide Technology focused on the structure, phase composition, and physical and chemical properties of nanopowders in high-temperature oxide systems. Those included oxides of aluminum, zirconium, and rare earth metals Al–Ce–O–Y–Zr [ 12 , 13 ] and Ce–O–Y–Zr [ 14 ].…”

The Ukrainian Phase Diagrams and Thermodynamics Commission has been a member of the Alloy Phase Diagram International Commission (APDIC) for almost thirty years (since 1994). APDIC unites 18 member organizations involving 26 countries. The main tasks of APDIC are the exchange of scientific information and coordination of the activities of the international scientific community, mainly in the field of state diagrams and phase thermodynamics. The annual report of the Ukrainian Commission on the results of the activities of Ukrainian scientists in this field in 2021 was presented at the APDIC meeting on May 27, 2022. This information is presented in a table, collecting data on the systems studied and the result obtained and containing a list of references to published papers. Scientists from the Frantsevich Institute for Problems of Materials Science (National Academy of Sciences of Ukraine, Kyiv), Taras Shevchenko National University of Kyiv (Ministry of Education and Science of Ukraine, Kyiv), and Donbas State Engineering Academy (Ministry of Education and Science of Ukraine, Kramatorsk) provided relevant information to the Ukrainian Commission.

The thermochemical properties of In—Pr system melts in the range of compositions 0 < xIn < 0,4 and In—Nd in the whole concentration range at 1573 ± 1 K were investigated by isoperibolic calorimetry. The obtained data for the In—Pr system melts were extrapolated to the unexplored concentration interval, taking into account that at xPr = 1 the integral and partial mixing for Pr enthalpy are equal to zero. It was found that the first partial for Pr and the minimum enthalpy of mixing are equal to –139 ± 11 and –40,3 ± 0,2 kJ / mol, respectively. For the In—Nd system the first partial for In and Nd, the minimum enthalpy of mixing is equal to −131,7 ± 11, −140,6 ± 12 і –43,3  0,2 kJ / mol, respectively. Comparison of ΔHmin, melts of the five previously studied In—Ln systems from the ordinal number Ln (zLn) together with the data obtained in this work showed that they are described by a single trend line. For ΔHmin of melts of In—Eu (Yb) systems there are very insignificant deviations from the trend line. But for the size factor, these deviations from the trend line are more significant. The enthalpies of formation of some intermetallics of In—Ln systems are known, and most of them belong to the compound LnIn3. But there is no complete agreement between these data. The results of the most modern work show less dependence on the serial number of lanthanide and are more exothermic for heavy lanthanides, compared with other data. Keywords: thermochemical properties, compounds, melts, In, Pr, Nd.
