Preparation of well dispersed suspensions suitable for spray drying |
摘要 |
A procedure for making well dispersed suspensions containing mixtures of powders displaying a low viscosity which remain stable over an extended period of time includes suspensions prepared in aqueous and/or ethanolic media using a cationic polyelectrolyte at the inherent pH of the mixture. The method is particularly useful for making robust slurries for subsequent spray drying of free flowing granules to be used in the fabrication of cemented carbide or cermet bodies.
