The crystallization kinetics of Zn(Met)SO_4·H_2O in mixed solvent of water with acetone

摘要

The crystal growth process of Zn(Met)SO_4·H_2O at 298.15 K is investigated by microcalorimetry. The rate constant of heat production (k_2) and the rate constant of crystal growth (k_1) during the crystallization process are 6.79·10~(-3) J s~(-1) and 11.21·10~(-3) s~(-1), respectively. The experimental results show the process accords with the Burton-Cabrera-Frank dislocation theory.
