Abstract : The patent concerns a method of preparing alkali metal halide powders which comprises reacting an alkali metal with an anhydrous alcohol and then reacting the resulting alkali metal alkoxide with dry hydrogen halide gas or silicon tetrahalide to form the alkali metal halide. An ultrahigh purity, anhydrous product is obtained in the form of a powder of submicron size that is particularly useful for high performance laser window-type applications.
