我们报告观察从室温静态重结晶实验（退火时间从几分钟到一年）冷压，合成，粗晶粒，湿氯化钠，制备宽离子束抛光和SEM观察在低温下直接观察晶界的盐水。在退火的所有阶段，样品中的大部分盐水沿沿着晶界在2D截面中连接。另一部分卤水是沿沿着晶界的孤立卤水包裹体阵列和迁移卤水填充晶界留下的卤水包裹体。这些边界中的大多数是移动的，因为聚集体是粗化的。我们解释说，没有可观察到的盐水膜的边界（
We report observations from room temperature static recrystallization experiments (annealing times from minutes to year) of cold-pressed, synthetic, coarse-grained, wet sodium chloride, prepared by broad ion beam polishing and SEM observations at cryogenic temperature to observe directly the brine in grain boundaries. At all stages of annealing, the majority of the brine in the samples is connected in 2D sections along grain boundaries. Another part of the brine is in isolated brine inclusion arrays along grain boundaries and in brine inclusions left behind by migrating brine-filled grain boundaries. Most of these boundaries are mobile because the aggregate is coarsening. We interpret that the boundaries without observable brine films (
