It has been found that on the cathodic polarization of a lead electrode in solutions of alkaline-earth metal (AEM) complexes (AEM= Mg, Ca, Sr, Ba) with ethylenediaminetetraacetic acid, modification of its surface takes place, which causes a change in hydrogen evolution overpotential. An effect of catalytic action of alkali and alkaline-earth metals (sodium) on the rate of electroreduction of silver thiosulfate complexes has been discovered. A hydrothermal method for the synthesis of nanostructured zirconium dioxide of predetermined modification from Ukrainian natural raw materials has been developed. The effect of alkali and alkaline-earth metal hydroxides and halides on the process of hydrothermal synthesis has been established. A phase diagram of the ternary system NaF-LiF-NdF3 has been constructed and studied for the first time. A mathematical model of electrooxidation of metals has been developed. Samples of ZBNL glass (the most promising optical materials, based on zirconium, barium, sodium and lanthanum fluorides, for making optoelectronic devices), in which barium and lanthanum fluorides are partially or fully substituted by fluorides of rare-earth elements in the lowest oxidation states (samarium, europium, thulium, ytterbium).
