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

在他们的研究中，他们计划：（1）继续一个积极的 计划的硼酸盐玻璃形成在一个非常广泛的 组合物的 使用辊式淬火器的高冷却速率将是 用于形成不超过75摩尔%的金属氧化物的玻璃。 待研究的系统包括硼酸铷和硼酸铯， 碱金属硼酸盐、硼硅酸盐和碱土金属硼酸盐。 （二） 对从步骤1得到的玻璃进行密度测量。 在获得密度数据后， 将寻求与锂一样的原子排列， 硼酸钠和硼酸钾。 （3）开始研究玻璃 使用新收购的Perkin Elmer 差示扫描量热仪（DSC 2）。 高碱含量 硼酸盐玻璃将进行研究，结果将是 在数量上与原子团有关。

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.
