text: In another aspect of this invention, a chemically precipitated luminescent grade cadmium sulfide is treated by a flowing stream of an inert gas at an intermediate temperature, thereafter the temperature is raised to a relatively high temperature while treating with a sulfide gas atmosphere selected from hydrogen sulfide and carbon disulfide, cooling the cadmium sulfide material to about the intermediate temperature in the sulfide atmosphere and thereafter cooling to ambient temperature in an inert gas.
