ABSTRACT:
Highly purified metal halide salts are made into a frangible stick having uniformly spaced lines of weakness which permit the stick to be broken readily into cylindrical pellets of uniform size. The pellets are particularly useful to supply the vaporizable fill in high intensity metal halide discharge lamps. The stick is formed by intermittently loading salt powder into the sized entrance to a channel through which the salt is forced, and compressing the charge against the back end of previously formed salt stick by means of a polished plunger.
