Abstrakt: Surface characteristics of particles and the intensity of particle interactions are presented as factors which may lead to caking of insoluble particles in aqueous dispersion. The degree of flocculation and the sediment volume were used as indexes of caking for sulfamerazine and bismuth subnitrate dispersions. Controlled particle flocculation by the addition of selected electrolytes produced a large volume of sedimented particles free from caking tendencies.
