Study on Crystallization Kinetics of Gypsum Prepared by Bittern under 30^oC and Different Stirring Speed

Abstract:

Crystallization kinetics experiment of calcium sulfate dehydrates, which is prepared by bittern under 30oC and different stirring speed conditions, is carried out. According to the results of the experimental data, the relationship of nucleus particle-number density n⁰ and crystal growth rate G with the residence time, temperature and the stirring speed is summarized. Also, the crystallization kinetics formula under 30oC and different stirring speed is given.
