The invention relates to the technical field of microcrystalline glass, and discloses a composition for glass, nano microcrystalline glass and a preparation method and application thereof. On the basis of the total mass of the composition for the glass, the composition for the glass contains 48 to 60 mass percent of SiO2, 25 to 35 mass percent of Al2O3, 5 to 10 mass percent of Na2O, 0 to 2 mass percent of K2O, 0 to 2 mass percent of B2O3, 2 to 6 mass percent of ZrO2, 1 to 3 mass percent of Li2O, 1.5 to 5 mass percent of TiO2 and 1 to 4 mass percent of P2O5. The nano microcrystalline glass formed by adopting the composition for glass provided by the invention not only has good light transmittance, but also has good mechanical properties such as drop resistance, compression resistance, aging resistance and the like. 本发明涉及微晶玻璃技术领域，公开了一种玻璃用组合物、纳米微晶玻璃及其制备方法和应用。以所述玻璃用组合物的总质量为基准，所述玻璃用组合物中含有48-60质量％的SiO2、25-35质量％的Al2O3、5-10质量％的Na2O、0-2质量％的K2O、0-2质量％的B2O3、2-6质量％的ZrO2、1-3质量％的Li2O、1.5-5质量％的TiO2和1-4质量％的P2O5。采用本发明提供的玻璃用组合
