Abstract:
Ef fects of surfactant s on three dispersion steps ( wett ing, dispersion, stabilizat ion) during the dispersion of ultrafine inorg anic powders in w ater is described, especially the mechanisms of dispersion stabilization and the funct ion of dispersants in dispersion stabilization. T he relation between molecular st ructures of surfactants and dispersity is also int roduced. T hree types of dispersants in inorganic powders aqueous slurries ( inorganic type, organic type and macromolecule type) are listed. The amount of dispersant is preliminarily discussed ( the optimum amount of dispersant, the relation betw een solid content and the opt imum amount of dispersant and the relat ion betw een part icle size and dispersant content ) .
