Effects of dispersant addition on the synthesis of indium-doped calcium zirconate by co-precipitation techniques

The synthesis of In2O3-doped CaZrO3 by solid oxide and oxalate co-precipitation routes has been studied. The effects of using polymeric surfactants (PEG) and ball milling on the synthesis were determined by characterizing the materials at various stages using SEM, XRD, FTIR and particle size analysis. PEG addition and ball milling led to the formation of smaller particles which reduces the time and temperature needed for perovskite formation.
