Abstract: Factors affecting the inter-particle forces between the colloidal BaTiOi parades were investigated in order to stabilise the suspension system for casting homogenous green bodies. Rheological measurements taken to assess the stability of BaTtO 3 particles against flocculation in aqueous medium were correlated with the Electro-kinetic Sonic Amplitude (ESA) to study the Electro-kinetic behaviour of the suspension. The aging kinetics of BaTiOs particles in aqueous systems was also monitored by' ESA and rheological measurements. The analysis of the supernatant solutions from suspensions showed that the concentration of Ba2+ ions in solution increased with decrease of the initial pH of the suspension.
