Sažetak
Slip casting is the most adequate technology for the production of complex ceramic components. It is a simple, reliable, flexible, cost-effective and pollution-free procedure, but it requires an adequate understanding of colloid suspensions and their behavior. Properties of ceramic products depend on the size of powder particles. When particles are smaller, the sintering is better and, consequently, product properties are better, too. On the other hand, particles smaller than 1 micrometer, in a combination with high suspension concentration, increase the suspension viscosity. It is a consequence of greater interactions among particles, which can lead to agglomeration or flocculation [1-3]. This interaction can be controlled with additives (dispersants). For a multi-component system, the selection of dispersant becomes more critical because it might be difficult to find a dispersant that is optimal for all components. In this research, the optimal amount of dispersant DOLAPIX CE 64 in alumina- zirconia suspensions was investigated.
