Abstract

The invention provides microcrystalline glass capable of separating out Mg3 (BO3) F3 nanocrystals and a preparation method of the microcrystalline glass, and belongs to the technical field of materialscience. The microcrystalline glass is prepared from the following components in percentage by mass: 50 to 65 percent of SiO2, 15 to 20 percent of H3BO3, 8 to 15 percent of MgF2, 8 to 15 percent of NaF and 0.01 to 1.5 percent of transition metal oxide. By optimizing a component formula in a SiO2-H3BO3-MgF2-NaF glass system, Mg3 (BO3) F3 nanocrystals are separated out of matrix glass for the firsttime, and the obtained transition metal ion doped microcrystalline glass with the Mg3 (BO3) F3 nanocrystals separated out has the ultra-wideband fluorescence property of 1000-1600 nm in a near-infrared region, is stable in structure and has a wide heat treatment temperature interval; and processing and manufacturing of transparent microcrystalline glass products are facilitated.
