The Effect of pH on the Suspension Properties and Homogeneity of Cast Green Bodies of Fine BaTiO3 in Suspending Aqueous Medium
Abstract
Factors affecting the inter-particle forces between the colloidal BaTiO3 particles were investigated in order to stabilise the suspension system for casting homogenous green bodies. Rheological measurements taken to assess the stability of BaTiO3 particles against fluctuation in aqueous medium were correlated with the Electro-kinetic Sonic Amplitude (ESA) to study the behaviour Electro-kinetic behaviour of the suspension. The aging kinetics of BaTiO3 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.
