Abstract
Adsorption behavior of two grades of poly(ethylene glycol) (PEG) was measur ed on silica and alumina in the presence of other organic and inorganic add itives commonly used in ceramic processing, A fractional factorial designed experiment showed that the level of adsorption was significantly influence d by the powder or powder blend and the binder, but was not influenced sign ificantly by small additions of auxiliary binder, surfactant, or the choice of deflocculant, Adsorption of PEG onto alumina was promoted by poly(acryl ic acid) deflocculant due to formation of an association complex between th e binder and adsorbed deflocculant molecules. A PEG compound containing an epoxide adsorbed at a higher level and the adsorption showed a larger pH de pendence than did a lower molecular weight PEG homopolymer.
