摘要：

This study examined the nucleation and growth behaviors of potassium alum crystals in a well-mixed continuous crystallizer. Crystal growth rates are size dependent and surface integration controlled. The higher temperatures enhance the growth rate but depress the nucleation rate. The interface supersaturation, which is identical with the overall supersaturation in this study, decreases as the temperature is increased under the constraints of constant retention time and magma density. The predicted kinetic behaviors influenced by temperature were found to be in agreement with those of experimental results.
