PROCESS FOR PRODUCING PHOSPHORESCENT BODY AND PHOSPHORESCENT BODY PRODUCED BY THE PROCESS, AND NAIL STONE INCLUDING PHOSPHORESCENT BODY

摘要

To provide a process for producing a phosphorescent body which allows efficient production of a granule-shaped phosphorescent body with a simple facility and a phosphorescent body produced by the process, and a nail stone including the phosphorescent body. In a process for producing a phosphorescent body containing at least a phosphorescent material and a glass material, at least the phosphorescent material and the glass material are mixed to give a paste mixture 2. A plurality of layers of the mixture 2 are stacked to form a granule-shaped laminate 3. The laminate 3 is sintered so that the laminate 3 is melted and shaped by the action of the surface tension of the melted laminate 3.
