Abstract

Glasses in the TeO₂–Ga₂O₃–M₂O (M═Li, Na, or K) systems were synthesized by a melt-quenching technique. The glass forming areas were delimited for each system. Systematic analyses were performed on two series of samples—the first one with a constant TeO₂/Ga₂O₃ ratio of 85/15, that is, [(TeO₂)_0.₈₅(Ga₂O₃)_0.₁₅]₁₀₀₋_x[M₂O]_x with 0 ≤ x ≤ 25 (with a step of 5 mol%), the second one with a constant alkaline oxide concentration of 10 mol%, that is, [TeO₂]_90-_y[Ga₂O₃]_y[M₂O]₁₀ with 5 ≤ y ≤ 15 (with step of 2.5 mol%). The values of the glass transition temperature, density, and optical transmission parameters (the positions of short- and long-wavelength absorption edge and the maximum transmittance value) were determined. The changes in these parameters were studied for varying glass compositions. In addition, the values of refractive index were measured at various wavelengths across the whole transparency region reaching from the visible up to the mid-infrared range.

TeO2-Ga2O3-M2O (M═Li、Na、K) 系玻璃的制备与表征

通过熔淬技术合成了 TeO2-Ga2O3-M2O （M═Li、Na 或 K）体系中的玻璃。每个体系都划定了玻璃形成区域。对两个系列的样品进行了系统分析--第一个系列的样品中 TeO2/Ga2O3 的比例恒定为 85/15，即[(TeO2)0.85(Ga2O3)0.15]100-x[M2O]x，0 ≤ x ≤ 25（步长为 5 摩尔%）；第二种样品的碱性氧化物浓度恒定为 10 摩尔%，即[TeO2]90-y[Ga2O3]y[M2O]10，5 ≤ y ≤ 15（步长为 2.5 摩尔%）。测定了玻璃转化温度、密度和光学透射参数（短波长和长波长吸收边的位置以及最大透射率值）。研究了这些参数在不同玻璃成分下的变化。此外，还测量了从可见光到中红外整个透明度区域内不同波长的折射率值。

期刊介绍： The International Journal of Applied Glass Science (IJAGS) endeavors to be an indispensable source of information dealing with the application of glass science and engineering across the entire materials spectrum. Through the solicitation, editing, and publishing of cutting-edge peer-reviewed papers, IJAGS will be a highly respected and enduring chronicle of major advances in applied glass science throughout this century. It will be of critical value to the work of scientists, engineers, educators, students, and organizations involved in the research, manufacture and utilization of the material glass. Guided by an International Advisory Board, IJAGS will focus on topical issue themes that broadly encompass the advanced description, application, modeling, manufacture, and experimental investigation of glass.
