manufacturing method and a crystal glass complex of crystal glass composite

摘要

Is a method for producing a crystalline glass composite having a light-emitting properties. This manufacturing method comprises the melting step and the forming step. The melt in the melting step, at least one of powdered B2O3 and SiO2, stores SrO and Al2O3 and powder mixture and are mixed Eu2O3 the melting furnace and the mixture so that the mixed phase of solid and liquid phases to. In forming step, and by cooling to below the glass transition point of the liquid phase after the melting step, Eu to form a added crystallized glass composites Eu is dispersed therein SrAl2O4 crystals were added to the glass. Furthermore, the melting step, to control the oxygen partial pressure in the atmosphere in the melting furnace to control the valence of Eu was added to the valence and SrAl2O4 crystals of Eu was added to the glass, respectively.
