High-alumina microcrystalline glass containing high-volume coal gangue and preparation method of high-alumina microcrystalline glass

The invention discloses high-aluminum microcrystalline glass with high-content coal gangue and a preparation method of the high-aluminum microcrystalline glass. The basic glass comprises the following components in percentage by weight: 50-70% of coal gangue, 8-25% of silica sand, 8-15% of sodium carbonate, 3-8% of calcite and 5-10% of calcium fluoride; the catalyst comprises the following oxides in terms of percentage by weight: 50 to 60 percent of SiO2, 10 to 20 percent of CaO, 5 to 10 percent of Na2O, 20 to 25 percent of Al2O3, 2 to 5 percent of F, 0 to 5 percent of MgO, 1 to 5 percent of K2O, 1 to 5 percent of Fe2O3 and 0 to 5 percent of TiO2. The coal gangue high-aluminum glass ceramic system designed by the invention is good in containment to coal gangue solid waste, high in absorptivity and excellent in mechanical property; by optimally designing glass basic components and a glass ceramic heat treatment system, large-mixing-amount and high-value utilization of the coal gangue solid waste can be realize
