The effect of polymerie flocculant on the uniformity of centrifugally formed green compacts was investigated. The compacts were obtained from heterogeneous ceramic powder slurries with different compositions and particle size distributions. When the content of eationic polymer, Cp, was>10^<-3> (g/g-powder) in welldispersed slurries containing aplite, alumina, and kaolin (with particle sizes in the range of 10^<-1>-10^1 μm in diameter), these powders floeeulated but the particle dispersion in the green compacts became uniform. This flocculation process in heterogeneous slurries added with a polymerie flocculant was effective in order to prevent segregation in the green compacts for mixtures of powders with different particle size.
