PROCESSES FOR PRODUCING Bi12MO20 PRECURSOR AND Bi12MO20 PARTICLE AND METHOD OF PRODUCING PHOTO-CONDUCTOR LAYER FOR CONSTITUTING A RADIATION IMAGING PANEL

摘要

PROBLEM TO BE SOLVED: To manufacture a photo-conductor layer high in the effect of collecting the formed electric charges, small in electric noise and comprising bismuth oxide type compound oxide.;SOLUTION: A mixed solution of a bismuth salt and a metal alkoxide is mixed together with an aqueous alkali solution to obtain a Bi₁₂MO₂₀ precursor, the resultant Bi₁₂MO₂₀ precursor is subjected to molding processing and the molded Bi₁₂MO₂₀ precursor is subjected to firing processing to produce the photo-conductor layer. Alternatively, the mixed solution of the bismuth salt and the metal alkoxide is mixed together with the aqueous alkali solution to obtain the Bi₁₂MO₂₀ precursor, the resultant Bi₁₂MO₂₀ precursor is subjected to heating processing in an alkaline liquid phase to make a particle or to firing processing to make the particle and the photo-conductor layer is produced by mixing the particle with a binder and applying it on a supporting body.;COPYRIGHT: (C)2006,JPO&NCIPI
