Abstract

A novel procedure for the formation of uniform, monodisperse, and single-phase zincite particles using soluble starch as crystallization additive is reported. At low starch concentrations, roughly spherical particles with a bimodal size distribution form. At high starch concentrations, the precipitate only contains large, approximately spherical particles with a monomodal and narrow size distribution. A simple precipitation–aggregation mechanism is postulated for particle formation.
