Abstract

<p>Lead iodide was precipitated from aqueous solutions of 0.015 - 0.1 M Pb(NO<sub>3</sub>)<sub>2</sub> and 0.03 - 0.2 M KI in the equimolar ratio using a laboratory model of a stirred continuous crystallizer at 22&nbsp;°C. After reaching the steady state, the PbI<sub>2</sub> crystal size distribution was measured sedimentometrically and the crystallization kinetics was evaluated based on the mean particle size. Both the linear crystal growth rate and the nucleation rate depend on the specific output of the crystallizer. The system crystallization constant either points to a significant effect of secondary nucleation by the mechanism of contact of the crystals with the stirrer blade, or depends on the concentrations of the components added due to the micromixing mechanism.
