Abstract
Ionic salts containing minor amounts of an activator and useful as scintillation phosphors are formed by extrusion of a macrocrystal of either a single crystal or a melt-grown multiple crystal ingot at a temperature below its melting point and under sufficient pressure to form a fully dense, homogeneous polycrystalline mass, the scintillation properties of which are essentially the same as, or better than, those of the original macrocrystal.
