The results of the investigations regarding the growth and the dissolution behavior of small sodium chlorate crystals at temperatures near saturation temperature of (31.00 +/- 0.02) degrees C are presented. Above this temperature all the observed crystals dissolved, as was expected. At temperatures between 30.5 degrees C and 31.0 degrees C coexistence of growing, non-growing and dissolving crystals was occurred. At temperatures below 30.5 degrees C dissolution of the crystals did not occur. A significant growth/dissolution rate dispersion existed at all temperatures. Possible reasons for simultaneous growth and dissolution are discussed. (c) 2013 Elsevier B.V. All rights reserved.
