Abstrakt: The behavior of uranium oxide-silica, zirconia-alumina, zirconia-iron oxide, uranium oxideiron oxide, zirconia-alumina-iron oxide, and uranium oxide-iron oxide-zirconia melts was experimentally investigated in the air. The existence of two-phase fluids in these systems was confirmed. It is proposed that the reason for the phase separation is the formation of complexes with the general formula x[MO] [MeO]. The influence of a complex concentration on the density and surface tension of melts in the ZrO-AlO system was demonstrated. [ABSTRACT FROM AUTHOR]
