Abstract
Precipitation of calcium and magnesium hydroxide from aqueous solution was carried out using a modified Nielsen apparatus in which supersaturation was established by rapidly mixing two reactant solutions in steady flow. The supersaturations (So) used were high enough to establish homogeneous nucleation. This was indicated by the observations: (a) the number of nuclei formed N was greater than 106/mL, (b) the So-N data were found to graph linearly on log(N)-[log(So)]-2 coordinates, and (c) the product entities exhibited highly monodispersed size distributions. Electron microscopic examination revealed that the morphologies for both products were determined by crystallographic structure. The mechanism of growth was found to change abruptly but only after the period of active nucleation. © 1989.
