Abstract: It is shown that the nature of processes in oxide solid-phase systems, primarily in nanosized ones, is determined by the behavior of the substance in a non-autonomous state. The composition of non-autonomous phases, the temperature of transition of non-autonomous phases to a liquid-like state, the equilibrium (locally equilibrium) and metastable thickness of non-autonomous phases, and the viscosity of the liquid-like nonautonomous phase are considered as the main parameters of non-autonomous phases.

Keywords: oxides, nanosystems, non-autonomous phase, melting point of the non-autonomous phase.
