Multi‐Scale Agglomerate Synthesis by Homogeneous Precipitation

Abstract

Zinc sulfide multiscale aggregates can be obtained by homogeneous precipitation in a stirred reactor. Particle size distributions and morphologies are studied as a function of several operating parameters: pH, concentration in reactants (thioacetamide and zinc sulfate), temperature and stirring rate. Four size scales are observed. Stirring rate and pH have an influence respectively on the largest and the smallest size scale. Concentration in thioacetamide has an effect on the largest scales. All size scales depend on temperature.
