摘要

摘要：氯酸钠是最常用于研究通过结晶自发破坏对称性的化合物。因此，了解固体颗粒的行为非常重要。本文研究了在水性无柄液滴中，NaClO3 晶体生长和溶解过程中的多次温度循环。冷却时，除了重复拉长的流体包裹体的典型形成外，在单晶体的边角处还会重复出现棱柱形流体包裹体 (PFI)。其基本机理涉及 (110) 面生长的完全终止和 {100} 面的传播，后者可以封闭 PFIs。本研究报告指出，加热时会形成瞬时甜甜圈状单晶体，即使不搅拌悬浮液也会导致单晶体分割。系统地添加其他具有不同氧化态氯原子的钠盐并没有改变这些观察结果。

NaClO3 Crystal Growth and Dissolution by Temperature Cycling in a Sessile Droplet

Abstract: Sodium chlorate is the most popular compound used to study spontaneous symmetry breaking by means of crystallization. Therefore, it is important to know the behavior of the solid particles. NaClO3 crystal growth and dissolution are investigated in an aqueous sessile droplet subjected to numerous temperature cycles. On cooling, in addition to the classical formation of repeated elongated fluid inclusions, there is a reproducible appearance of prismatic fluid inclusions (PFIs) at the corners of single crystals. The underlying mechanism involves the complete termination of the (110) face growth and the propagation of the {100} faces, which can close the PFIs. This study reports that on heating, transient donut-like single crystals formed, which could lead to their segmentation, even without stirring the suspension. The systematic addition of other sodium salts with chlorine atoms at different oxidation states did not change these observations.
