摘　　要：【目的】以KNO_(3)/NaNO_(3)混合熔盐增强盖板玻璃的离子交换深度及力学性能。【方法】采用低温离子交换法对铝硅盖板玻璃进行化学强化,并在玻璃料方中添加Li_(2)O,对玻璃进行二次强化。【结果】在玻璃料方中添加Li_(2)O后进行的二次强化工艺能够显著提高玻璃的离子交换深度,同时保持其优良的力学性能。相比于传统的低温离子交换法,二次强化工艺在提高玻璃性能的同时,避免了可能导致玻璃变形和表面缺陷的高温处理过程。【结论】通过在玻璃料方中添加Li_(2)O的二次强化工艺制备的锂铝硅盖板玻璃具有较大的离子交换深度,同时该玻璃的抗冲击强度等力学性能得到了显著增强。该玻璃在航空航天领域、交通领域、电子产品及清洁能源等领域具有广泛的应用前景。[Purposes]This paper aims to enhance the ion exchange depth and mechanical properties of the cover glass by selecting KNO_(3)/NaNO_(3) as molten salt.[Methods]Aluminumsilicon cover glass was chemically strengthened by a low-temperature ion exchange method.Li_(2)O was added to the glass formula for secondary strengthening of the glass.[Findings]The ion exchange depth of the glass can be significantly improved by adding Li_(2)O to the glass formula while maintaining its excellent mechanical properties.Compared with the traditional low-temperature ion exchange method,secondary strengthening method not only improves glass performance but also avoids the high-temperature processes that may cause glass deformation and surface defects.[Conclusions]The lithium-aluminum-silicon cover glass prepared by adding Li_(2)O for secondary strengthening demonstrates high impact resistance and other mechanical properties,showing a wide range of application prospects in the fields of aerospace,transportation,electronic products,and clean energy.
