The ubiquitous nature and unusual properties of water have motivated many studies on its metastability under temperature- or pressure-induced phase transformations. Here, nanosecond compression by a high-power laser is used to create the nonequilibrium conditions where liquid water persists well into the stable region of ice VII. Through our experiments, as well as a complementary theoretical-computational analysis based on classical nucleation theory, we report that the metastability limit of liquid water under nearly isentropic compression from ambient conditions is at least 8 GPa, higher than the 7 GPa previously reported for lower loading rates.

动态压缩下液态水冻结成冰 VII 的亚稳定性

水无处不在的性质和不寻常的特性激发了对其在温度或压力诱导相变下的亚稳定性的许多研究。在这里，高功率激光的纳秒压缩用于创建非平衡条件，其中液态水可以很好地持续进入冰 VII 的稳定区域。通过我们的实验以及基于经典成核理论的补充理论计算分析，我们报告说，液态水在来自环境条件的近等熵压缩下的亚稳态极限至少为 8 GPa，高于先前报道的 7 GPa加载率。
