Analysis on Crystallization Kinetics of Gypsum Prepared by Bittern under 40°C

Abstract:

Crystallization kinetics experiment of calcium sulfate dehydrates, which is prepared by bittern under 40oC and 200r/min 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 is summarized. Also, the average diameter of gypsum crystal is decreasing with the residence time increase. Meanwhile, the crystallization kinetics formula is derived to be: B⁰=3.20×10⁵G^0.⁴⁷.
