Abstract
Growth and dissolution rate dispersion of boric acid single crystal was investigated in supersaturated and undersaturated solution contained in a specially designed cell by in situ examination of crystals mounted at the tip of a needle, rotated between 0° and 360° and using an image analyzer system. Changes in the behavior of equivalent crystal diameters at different supersaturation and undersaturation and rotation angles were determined by using two new procedures: (1) rotating growing or dissolving crystals by 360° at intervals of 45° (Procedure 1: angular growth/dissolution rates), and scanning individual face at increments of 10° in the 360° range (Procedure 2: point growth/dissolution rates). It was found that: (1) dispersion in angular growth and dissolution rates is a general phenomenon due to different growth and dissolution rates of individual faces of a crystal, but this dispersion is reduced when the average growth and dissolution rates of all faces are taken into account, and (2) the point growth/dissolution rates of single crystal, calculated by procedure 2, are different from point to point.
