Summary: | The invention relates to the technical field of microcrystalline glass, in particular to LAS nanocrystalline glass and a preparation method thereof. The LAS nanocrystalline glass is prepared from the following raw materials: 50-65 wt% of SiO2; the content of Al2O3 is 22 to 28 weight percent; 6 wt%-10 wt% of Li2CO3; sb2O3 is greater than 0 wt% and less than or equal to 1 wt%; na2O is greater than 0 wt% and less than or equal to 4 wt%; znO is greater than 0 wt% and less than or equal to 4 wt%; zrO2 is greater than 0 wt% and less than or equal to 4 wt%; tiO2 is greater than 0 wt% and less than or equal to 4 wt%. The transparent LAS nanocrystalline glass is prepared from specific components in a specific ratio, and the prepared LAS nanocrystalline glass is uniform in grain size, relatively high in light transmittance and relatively low in thermal expansion coefficient by adopting electric-thermal field coupling treatment.
