Abstract
A method of manufacturing an output phosphor screen for x-ray image intensifier is disclosed. The method includes the steps of dropping a dispersion of infusible spherical silicon resin particles on a water surface to form an aggregate layer of the infusible spherical silicon resin particles on the water surface. Thereafter, the aggregate layer of infusible spherical silicon resin particles in adhered on a face plate. The adhered aggregate layer is the calcinated in an atmosphere containing oxygen at a temperature of not less than 500.degree. C. to change the aggregate layer of infusible spherical silicone resin particles into a layer of spherical silica particles. A phosphor layer is then formed on the spherical silica particle layer.
