Process for preparation of photoconductive powders of cadmium sulfide type materials

摘要

A process for preparation of photoconductive powders of a cadmium sulfide type material comprising firing cadmium sulfide type material in an oxygen-containing atmosphere in the presence of a dispersant at a temperature at which the substance to be fired does not melt. The fired substance is water washed in order to remove the dispersant therefrom, if it is water soluble.
