Abstract:
In a method of forming a particle suitable for introducing lamp fill material into a gaseous discharge lamp determinative of the spectral characteristics of the lamp, the method including the steps of (i) providing a lamp spectral characteristic determinative fill material comprising one or more metal halides; (ii) melting the fill material; and (iii) forming a particle from the melted fill material, the improvement comprising the step of admixing a strengthening agent to the fill material in an amount sufficient to comprise between about 0.25 and 5.0 mole percent of the admixture, the strengthening agent being added to the fill material prior to the step of melting the fill material so that the particle is formed from the melted admixture, the strengthening agent comprising one or more metal halides from the group consisting of gold halide, silver halide, and copper halide.
