Popis:	A new preparing process of photoconductive CdSe powders suitable for an EL-PC-type X-ray image converting panel was proposed.The influence of parameters such as amount of flux and activator in the raw mixture, firing temperature and firing atmosphere on the photoconductive characteristics was investigated. To keep the amount of flux minimum was not only effective to improve the photosensitivity, threshold voltage and granularity of resultant photoconductive powders but also effective to make the preparing process simple and reliable.Applying such improved photoconductive powders to a solid-state X-ray image converting panel, the brightness and resolution of the panel was remarkably improved.
