Abstract[Bearbeiten]
Experiments on evaporation of aqueous sodium chloride solutions from micro capillaries demonstrate for the first time that there is a metastability limit to the solubility of NaCl. The supersaturation of the solution reached at the onset of crystallization is found to be very high, almost twice the saturation concentration. At this concentration, we observe a peculiar form of crystal growth: the very rapid growth of a single Hopper crystal in which many crystallites grow outwards from a single central nucleus. The high supersaturations achieved at the onset of crystal growth are found to be independent of the size, shape and surface properties of the micro capillary.
