Understanding composition‐structure‐property relationships of high‐alumina nuclear waste glasses are important for vitrification of nuclear waste at the Hanford Site. Two series of glasses were designed, one with varying Al:Si ratios and the other with (Al + Na):Si ratios based on the international simple glass (ISG, a simplified nuclear waste model glass), with Al₂O₃ ranging from 0 to 23 mol% (0 to 32 wt%). The glasses were synthesized and characterized using electron probe microanalysis, X‐ray photoelectron spectroscopy, small angle X‐ray scattering, high‐temperature oxide melt solution calorimetry, and infrared spectroscopy. Glasses were crystal free, and the lowest Na₂O and Al₂O₃ glass formed an immiscible glass phase. Evolution of various properties—glass‐transition temperature, percentage of 4‐coordinated B, enthalpy of glass formation—and infrared spectroscopy results indicate that structural effects differ based on the glass series.

Al：Si和（Al + Na）：Si比对国际简易玻璃性能的影响，第一部分：物理性能

了解高氧化铝核废料玻璃的成分-结构-性质之间的关系对于汉福德基地的核废料玻璃化非常重要。根据国际简单玻璃（ISG，一种简化的核废料模型玻璃），设计了两种玻璃，一种具有不同的Al：Si比，另一种具有（Al + Na）：Si比，Al ₂ O ₃为0至23mol％（0至32wt％）。使用电子探针显微分析，X射线光电子能谱，小角度X射线散射，高温氧化物熔体溶液量热法和红外光谱对玻璃进行了合成和表征。玻璃不含晶体，最低的Na ₂ O和Al ₂ O ₃玻璃形成不混溶的玻璃相。玻璃转变温度，4配位的B的百分比，玻璃形成的焓等各种性质的演变以及红外光谱结果表明，结构效应因玻璃系列而异。
