Tempered glass, microcrystalline glass and preparation method and application thereof

The invention relates to tempered glass, microcrystalline glass and a preparation method and application thereof. The microcrystalline glass is prepared from the following components in percentage by mass: 54 to 66 percent of SiO2, 17 to 28 percent of Al2O3, 0.5 to 4 percent of MgO, 2 to 8 percent of Na2O, 2 to 6.5 percent of Li2O, 0.5 to 2 percent of P2O5 and 1 to 5 percent of TiO2, wherein the crystalline phase of the microcrystalline glass comprises beta-spodumene. The microcrystalline glass comprises the following components in specific content: SiO2, Al2O3, MgO, Li2O, Na2O, P2O5 and TiO2, and the crystalline phase of the microcrystalline glass comprises beta-spodumene. After being chemically strengthened, the microcrystalline glass has relatively high pressure stress and relatively good crack propagation resistance; therefore, the glass has better impact resistance, is not easy to break to generate fine glass fragments after being impacted, and is higher in use safety. 本发明涉及一种强化玻璃、微晶玻璃及其制备方法与应用。该微晶玻璃，按照质
