The Synthesis of Crystals of Chalcogenides of K, Zr, Hf, Hg, and Some Other Elements in Halide Melts under Conditions of Stationary Temperature Gradient

Abstract

The growth of crystals of metals, alloys, chalcogenides, and pnictides in melts of alkali metal halides under conditions of stationary temperature gradient has been studied. The formation of crystals with participation of elements that were not considered in previous studies (mercury, zirconium, hafnium, germanium, sodium, potassium, rhenium, and osmium) is described. Mechanisms of element transport in salt melts are proposed. It is shown that most of crystals are obtained from ions in which necessary elements exist in most conventional oxidation states.
