GROWTH AND PROPERTIES OF II-VI COMPOUNDS.

Abstract

The preparation of powders of II-VI compounds of high purity was investigated. The group II metal starting material was purified by repeated distillation under argon. Purities of 99.99% were attained. Various methods of synthesis of the compounds were evaluated with regard to maintaining purity and additional purification. Hydrogen reduction of the chalcogenates was selected, resulting in powders with a total impurity content of less than 40 ppm. Attempts to grow single crystals were only partly successful due to the highly refractory nature of the compounds. Small single crystals of barium sulfide were obtained, however, they are heavily contaminated with tungsten. (Author)
