The effect of polyvinylpyrrolidone (PVP) on rheology of aqueous SiC suspensions with polyethylene glycol (PEG) as binder was investigated. Results showed that in presence of PEG as binder, suspensions with addition of PVP at proper dosages resulted in better dispersion in comparison with conventional dispersant polyacrylic acids (PAA). As the total content of dispersants was fixed, PVP and PEG co-existing...
With the addition of poly(vinylpyrrolidone) (PVP) as a second dispersant, the rheological behaviors of SiC suspensions dispersed with copolymer acrylic acid/2-acrylamido-2-methylpropane sulfonic acid sodium (AA/AMPS) in both acid and neutral condition were further improved remarkably. In the presence of PVP with small amount (0.1wt%), yield stress of SiC suspensions was much lower than that dispersed...
