Outline of Final Research Achievements

We propose a novel method, termed “glass-flux growth,” for fabrication of composite materials formed by crystals and glass matrices with different chem-ical phases, with well-connected and pure interfaces. In traditional flux method, the remaining fluxes are removed from the final products to isolate the target crys-tals. We expect that if the flux itself can form functional glass phases, the flux method can fabricate a variety of crystal-glass composites. Herein, we fabricated a compo-site of lithium transition metal oxide crystals and glass ma-trix by the glass-flux growth process. Their interfaces were well-connected and very smooth, without impurity phases. The glass-flux method is very simple, inexpensive, envi-ronmentally-friendly, like the traditional flux method. In future, the use of such “glass-flux growth” processes will become increasingly important in the fabrication of vari-ous functional material composites.
