Abstract : Three methods of growing CaO, SrO and BaO single crystals were investigated. The failure of all crucibles materials to withstand chemical attack by these oxides when molten prevented the Czochralski techinique from working. Vapor phase growth was unsatisfactory due to reaction of the transported material with the growth tube. A plasma torch method in which the oxide powder and the plasma are separately injected into the growth region offers promise, but time available did not permit perfection of this technique. (Author)
