ABSTRACT:
Apparatus for producing purified metal halides, such as sodium iodide and mixtures of sodium iodide and mixtures of sodium iodide with scandium iodide, of accurately controlled particle size, particularly useful as a vaporizable fill for high pressure discharge devices. The apparatus may include means for evaporating volatiles from the solid impure metal halide, melting the impure halide, passing hydrogen, hydrogen halide, hydrogen and halogen, or mixtures thereof through the halide, and then passing the molten halide through a vibrating discharge conduit or nozzle into an inert quenching atmosphere to form the particles of purified halide.
