Abstract:

Single crystals of binary and ternary compounds of alkaline earth and a chalcogen, with or without a transition element are grown by charging a reaction vessel with an alkaline earth chalcogenide, with or without a transition element or a halide thereof, an acidic mineralizer and anhydrous ammonia to where the fill factor in the reaction vessel is 30-95 sealing the reaction vessel to the outside atmosphere heating the contents of the reaction vessel to a temperature of at least 300 deg C. until single crystal materials visible to the eye form in the reaction vessel cooling the contents of the reaction vessel and extracting the single crystal materials from the reaction vessel.
