Abstract

The effect of various alkali metal content (Li, Na) in high-alumina-silicon cover glass on the structure and performance of the glass is investigated in this work. The findings of the performance investigation show that the density, chemical stability, and thermal expansion coefficient of glasses display nonlinear changes. In addition, the typical thermal and dielectric properties are unaffected by combined alkali. The integrity of the glass network structure and the tightness of ions alternately vary due to the influence of lithium ion's own features, which is origin of MAE according to the results of XPS and infrared spectroscopy. It is certain that altering the Li/Na ratio can optimize this type of glass, and the defined range has guiding relevance for the design and production of cover glass.
