Electrochemical Reduction of La₂O₃, Nd₂O₃, and CeO₂ in LiCl-Li₂O Melt by Alexey V. Shishkin, Vladimir Yu. Shishkin, Aleksandr A. Pankratov, Anna A. Burdina, Yuriy P. Zaikov

“…The reduction degree of rare-earth metal (REM) oxides was determined using both the bromine method and reduction melting of the samples in the graphite crucible. The formation of the metallic phase composed of the rare-earth elements (REEs) was not observed even at the cathode potentials, corresponding to the formation of the liquid alkali metal phase, and lithium extraction, which, in the quantitative ratio, exceeds greatly the values needed for the reduction reaction. …”

Effect of the Degree of Li₃PO₄ Vapor Dissociation on the Ionic Conductivity of LiPON Thin Films by Alexander Kamenetskikh, Nikolay Gavrilov, Alexey Ershov, Petr Tretnikov

“…This paper presents the results of a study on the plasma composition during anodic evaporation of Li₃PO₄ in a discharge with a self-heating hollow cathode and a crucible anode. A method is proposed for adjusting the free lithium concentration in the gas-vapor (Li₃PO₄ + N₂/Ar) discharge plasma based on changing the frequency of collisions of electrons with Li₃PO₄ vapor in the anodic region of the discharge. …”
