    摘要: A method for producing a ceramic scintillator comprising the steps of mixing a rare earth compound with sulfuric acid and/or sulfate to cause their reaction to obtain a product; calcining the product to obtain calcined powder; reducing the calcined powder to obtain rare earth oxysulfide powder; molding the rare earth oxysulfide powder to obtain a green body; and sintering the green body; a pulverization step being conducted to adjust the particle sizes of the product and/or the calcined powder at least before the reduction step. Translation of the Abstract as published by WIPO This method for producing a ceramic scintillator includes: a mixing step for obtaining a product by mixing and reacting a rare earth compound and sulfuric acid and/or a sulfate; a calcining step for obtaining a calcined powder by calcining the product; a reduction step for obtaining a rare-earth oxysulfide powder by reducing the calcined powder; a molding step for obtaining a molded article by molding the rare-earth oxysulfide powder; and a sintering step for sintering the molded article. Furthermore, the method for producing a ceramic scintillator is characterized by including a pulverization step for adjusting the particle diameter of the product and/or the calcined powder prior to at least the reduction step.
