通过共混对材料的玻璃化转变温度(Tg)和性能进行物理改性是工业界和学术界的普遍做法，具有很大的经济优势。在这种情况下，通过混合从现有的玻璃成分中简单地生产迄今无法获得的新的无机玻璃混合物，带来了很大的希望，有可能提供具有新的和改进的性能的新玻璃，这是经典玻璃合成无法实现的，用于诸如计算机屏幕、玻璃-金属密封件和核废料存储材料等大量应用。在这里，我们证明了所研究的特定玻璃成分的混合物在所有比例下都是可混溶的，这在玻璃等坚硬凝聚物中是一个未被报道的现象。有趣的是，得到的数据与理论方程(补充信息)计算的TGS之间的良好一致性，用于预测具有弱但显著特定相互作用的共混物的玻璃化转变温度与组成的关系。这种混合方法目前还不适用于无机玻璃，这反映了这样一个事实，即相对较低玻璃化温度的耐水和耐化学腐蚀的磷酸盐玻璃是最近才出现的。
The physical modification of glass transition temperature (Tg) and properties of materials via blending is a common practice in industry and academia and has a large economic advantage. In this context, simple production of hitherto unattainable new inorganic glass blends from already existing glass compositions via blending raises much hope with the potential to provide new glasses with new and improved properties, that cannot be achieved with classical glass synthesis, for a plethora of applications such as computers screens, glass-to-metal seals, and storage materials for nuclear wastes. Here, we demonstrate that blends of the specific glass compositions studied are miscible in all proportions, an unreported phenomenon in hard condensed matter like glass. Interestingly, excellent agreement was found between the obtained data and calculated Tgs from theoretical equations (Supplementary information) for predicting the composition dependence of Tg for miscible blends with weak but significant specific interactions between the blend components. That this blending method is at present not applied to inorganic glasses reflects the fact that water and chemically resistant phosphate glasses with relatively low Tgs have become available only recently.
