An improvement is disclosed in a process for the manufacture of metal halide particles containing at least one lanthanide metal halide in which the metal halide is melted and passed through a discharge conduit into an inert, quenching atmosphere. The improvement comprises adding a minor amount of hydrogen halide (the halide radical of the lanthanide metal halide and of the hydrogen halide being of the same halogen species) to the molten lanthanide metal halide to promote wetting of the molten lanthanide metal salt on the discharge conduit. The resulting particles show excellent uniformity of particle size and size distribution.
