The viscosity of Y{sub 2}O{sub 3}-ZrO{sub 2} suspensions with 50-75 wt.% solid in a toluene-based solvent has been determined using oleic acid, glycerol trioleate and menhaden fish oil as dispersants. Oleic acid is the most efficient dispersant for the given solvent-powder system. Dispersions with oleic acid show the lowest viscosity, exhibiting a minimum at a dispersant/powder ratio of 0.6 wt.%. The viscosity of tape casting slips reaches a minimum at the same dispersant/powder ratio.
