Abstract
An improved flux for use in preparing X-ray phosphors comprises an alkali metal sulfate, an alkali metal metaborate and, optionally a strontium halide. By varying the concentration of the metaborate and strontium halide in the flux composition, the size and dry bulk density of the phosphor particles and the speed of the phosphor, respectively, can be controlled. Also disclosed is a process of making phosphors using the above flux, and X-ray intensifying screens containing such phosphors.
