| Abstract: | To advance the rheological quality of yttria suspensions, the effects of three dispersants were evaluated and compared. It was found that after adding each of these dispersants, zeta potential moved toward negative direction and the pHIEP shifted from basic to acidic. An increase of the pH could increase the absolute zeta potential. The fluidity and stability of yttria suspensions were examined by viscosity measurements and sedimentation tests. |
