Title:
SPHERICAL PARTICLE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2013/133357
Kind Code:
A1
Abstract:
A glass particle manufacturing method comprises: preparing a molten liquid that is a uniform composition consisting of a liquid phase A which contains B2O3 as one component; producing an emulsion that is a composition consisting of a liquid phase B which is a dispersion medium and a liquid phase C which is a dispersoid caused by phase separation in the liquid phase A; cooling the emulsion to solidify the liquid phase B and the liquid phase C into a solid phase B and a solid phase C that are glass respectively corresponding to the liquid phase B and the liquid phase C, thereby obtaining a solid dispersed system in which the solid phase C which is a dispersoid is dispersed in the solid phase B which is a dispersion medium; and treating the solid dispersed system with a solvent with respect to the solid phase B to dissolve and remove the solid phase B and recover the solid phase C.
