Effects of calcination conditions on phase and morphology evolution of lead zirconate powders synthesized by solid-state reaction
Lead zirconate (PbZrO3) powder has been synthesized by a solid-state reaction via a rapid vibro-milling technique. The effects of calcination temperature, dwell time and heating/cooling rates on phase formation, morphology, particle size and chemical composition of the powders have been investigated...
