Elucidating the influence of molten salt chemistries on the synthesis and stability of perovskites oxides.

In this work, we investigate the synthesis of (LaSr)MnO (LSM) in various molten salts to gain insight on the influence of molten salt ions for synthesizing materials critical for energy applications. LSM nanoparticles with a size range of ∼10-200 nm and with target stoichiometries were formed from oxide precursors feeding into KNO. Furthermore, feeding precursors into the melt compared to mixing and heating from room temperature results in complete formation of LSM that was otherwise unattainable using conventional molten salt synthesis methods.
