蠕变是从溶液制备晶体中众所周知但令人讨厌的现象，其中生长的微晶逐渐沿着生长容器的壁向上延伸。在这个过程中，溶液被输送到蠕动微晶的尖端，在那里发生溶剂蒸发并沉积固体材料。在这项研究中，从蒸发液滴的离子盐的饱和水溶液中，放置在不同的基板材料的晶体聚集体的生长，已使用光学显微镜进行了研究。结果表明，结晶过程的速率决定步骤是溶液的蒸发，遵循菲克定律。继续生长过程所需的新鲜溶液由沿生长微晶沿着流动的液体提供。这可以发生在微晶的旁边和顶部（顶部供应蠕变，TSC）或微晶和衬底之间的狭窄空间（底部供应蠕变，BSC）中。发生率、模式（TSC或BSC）和...
Creeping is a well-known but annoying phenomenon in the preparation of crystals from solution, where growing crystallites gradually extend up the walls of the growth vessel. In this process, solution is transported toward the tip of the creeping crystallites, where solvent evaporation takes place and solid material is deposited. In this study, the growth of crystal aggregates extending from evaporating droplets of saturated aqueous solutions of ionic salts, placed on different substrate materials, has been investigated using optical microscopy. It is shown that the rate determining step of the crystallization process is the evaporation of solution, following Fick’s laws. Fresh solution, necessary to continue the growth process, is supplied by liquid flow along the growing crystallites. This can take place aside and on top of the crystallites (top supplied creeping, TSC) or in the narrow space between the crystallites and the substrate (bottom supplied creeping, BSC). The occurrence, mode (TSC or BSC), and...
