Abstract:

Literature surveys were made in preparation for an experimental study directed toward the production of high purity Ba metal. The pertinent physical and chemical properties of Ba metal and the principal Ba compounds organic and inorganic are summarized. Fifteen inorganic and 8 organic compounds are discussed. A comprehensive survey was made of methods for separation of Ba from Ca and Sr. The principal methods for the preparation of Ba metal include fused salt electrolysis and reduction of Ba compounds such as the oxide with Al, Mg, Si and their compounds or alloys in vacuo. No good methods for the separation of Ba from Ca and Sr were reported. A bibliography on the separation of Ba from Ca and Sr is presented which includes 9 chemical, 6 chromatographic, and 5 ion exchange methods.
