Na2O/Li2O Ratio Dependency on the Thermal, Mechanical, Dielectric Properties and Chemical Stabilities of Li2O-Al2O3-SiO2 Glass
文献摘要：
Li2O-Al2O3-SiO2 based glasses were investigated as potential protection glass for electronic devices due to their excellent mechanical properties, such as high hardness, toughness, and scratch resistance. In this paper, Li2O-Na2O-Al2O3-SiO2 glass with different Li2O/Na2O ratio components were prepared by melt-quenching method, and the effects of Na2O/Li2O ratio on the glass densities, structure, thermal, mechanical properties, and chemical stabilities were studied. The experimental results indicate that the glass transition temperature increases with the increases in Na2O/Li2O ratios, due to larger ion radius. While the thermal expansion coefficient slightly decreases from 11.4 × 10-6 to 11.09 × 10-6 /℃. The elastic modulus increases from 57 to 72 GPa. The bending strength reaches maximum 80.90 MPa when the Na2O/Li2O ratio is 1.7, then decreases as the ratio further increases. In addition, the Vicker's hardness gets to 7.37 GPa with largest Na2O/Li2O ratio. Moreover, the dielectric loss and dielectric constant increases as the ratio increases. The Raman structure analysis shows the Q4 [Si-O-Si] decreases as Na2O/Li2O ratio increases, which is responsible for the characteristic properties change. Moreover, the glass shows lowest mass loss in 10vol％ HF solutions when the ratio is 1.4, while 1.7 in 5wt％ NaOH solution.
