Abstract

Nanocrystalline BaTiO ₃ particles have been prepared by the ambient condition sol (ACS) process that involves chemical precipitation of a titania gel and heated reflux processing of the gel in a Ba ²⁺ containing solution. Among the processing variables, higher initial pH and Ba/Ti molar ratio led to smaller crystallite size of BaTiO ₃ powders. The morphology of the BaTiO ₃ powders was affected by the anion groups in the precursor species. Organic mineralizer, tetramethylammonium hydroxide (TMAH), can adsorb on the BaTiO ₃ nuclei and further inhibit particle growth. Addition of a polymer dispersant during BaTiO ₃ synthesis led to a smaller particle size and increased redispersibility of the particles in water.
