RUI: Density and Glass Transition Temperatures of Borate Glasses Related to Atomic Arrangements

在他们的研究研究中，他们计划：(1)继续在非常广泛的成分范围内形成硼酸盐玻璃的有力计划。使用辊式淬火机的高冷却速度将被用来形成高达75%摩尔金属氧化物的玻璃。要研究的体系包括：硼酸锶和铯、混合碱式硼酸盐、硼硅酸盐和碱土硼酸盐。(2)从第一步开始对得到的玻璃进行密度测量。在确保密度数据之后，将寻求与原子排列的定量联系，就像对锂、钠和钾所做的那样。以及(3)使用新获得的Perkin Elmer差示扫描量热仪(DSC2)开始研究玻璃化转变温度。将研究高碱含量的硼酸盐玻璃，结果将与原子基团定量相关。

In their research study they plan to: (1) continue a vigorous program of borate glass formation over an extremely wide range of compositions. High cooling rates using a roller-quencher will be employed to form glasses out to 75 molar percent metal oxide. Systems to be studied include rubidium and cesium borates, mixed alkali borates, borosilicates, and alkaline earth borates. (2) make density measurements on the resulting glasses from step 1. After securing the density data, quantitative connections with atomic arrangements will be sought as was done with lithium, sodium, and potassium borates. and (3) begin a study of glass transition temperatures using a newly acquired Perkin Elmer Differential Scanning Calorimeter (DSC2). High alkali content borate glasses will be studied and the results will be quantitatively related to atomic groupings.
