Abstract
We have discovered that alkali halides may be purified, particularly of trace anionic and cationic impurities, by scrubbing a melt of the alkali halide with gaseous nascent halogen. The halide radical of the gaseous nascent halogen preferably corresponds to the halide radical of the alkali halide. The purified material may then be used to form single crystals from which laser windows may be produced.
