The in-situ exfoliation of graphite in molten NaCl–KCl salt at 750 °C yielded a homogeneous composite, from which graphene nanoplatelets (GnP) could be easily and completely separated. The GnP product displayed relatively large-size particles (12
Effect of salt type on the particle size of LaMn1-xFexO3 (0.1≤x≤0.5) synthesized in molten chlorides

LaCoO3 perovskite was successfully synthesized in molten NaCl–KCl eutectic mixture. Heating the La-nitrate, Co-nitrate and NaCl–KCl mixture to 800 °C yielded large (up to 5 microns) LaCoO3 cubic particles. Conversely, when La- and Co-nitrates we
