Molten oxide membranes (MOMs) are a new class of ion transport inorganic membranes which demonstrate superior oxygen selectivity and permeability and could be used in electrochemical devices such as molten oxide fuel cells (MOFCs) and oxygen separators for energy conversion and air separation, respectively [Acc. Chem. Res., 50, 273 (2017)]. However, oxygen ion transport mechanisms in MOM materials are not clear enough. Understanding the oxygen ion transport mechanisms in molten oxides is important for the discovery of new MOM materials with enhanced performances that can enable the operation of the electrochemical devices more efficiently. Here we suggest an approach that adapts a dynamic polymer chain model, developed for specific molten oxides, to a wide range of melts. This generic model can evaluate the oxygen permeation fluxes through different MOM materials that are comparable to experimental data. The study of ion transport membrane (ITM) materials and processes is a rapidly expanding research interest field. This is due to the fact that the ITM-based technology modules have the potential to improve the efficiency and environmental performances of energy generation systems.1,2 ITM can separate high purity oxygen from air at elevated temperatures and have the potential to reduce the cost of oxygen production in comparison with the conventional cryogenic process.3 The mixed-conducting perovskite-type compounds, 4,5 ceramic composites, 6-9 and cermets 10-13 are used as ITM materials. The practicalities for incorporating ceramic membrane materials into industrial processes are discussed in comprehensive reviews. 1,2Recently, the molten oxide membrane (MOM) materials have been developed. 14,15 This MOM materials consist of solid grains and intergranular liquid channels. The intergranular liquid channels provide the membrane material high ionic conductivity, gas tightness, and ductility. This last property allows us to deal successfully with the problem of thermal incompatibility (difference in coefficient of thermal expansion, CTE).There 14,15 Transport properties (electrical conductivity, oxygen ion transport number, and oxygen and nitrogen permeation fluxes) of these MOM materials have been measured.

Recently, a dynamic polymer chain model for oxygen ion transport in molten V 2 O 5 has been developed.

“…

Copper may experience catastrophic oxidation in the presence of low-melting oxides (MoO 3 , V 2 O 5 , Bi 2 O 3 , etc.) at elevated temperature in an oxidizing environment [1][2][3]. These oxides are frequently formed in various cooling devices (space technology and nuclear power engineering), where copper operates in contact with a refractory metal (Mo, V, W, etc), and in copper metallurgy.
