Effects of Vibro-Milling Time and Calcination on Phase Formation and Particle Size of Lead Zirconate Nanopowders

Abstract

Effect of calcination conditions on phase formation and particle size of lead zirconate (PbZrO ₃ ) powders synthesized by a solid-state reaction with different vibro-milling times was investigated. It was found that the calcination time for the formation of pure PbZrO ₃ was lower when longer milling times were applied. More importantly, by employing an appropriate choice of the milling time and calcination conditions, PbZrO ₃ nanopowders have been successfully prepared with a simple solid-state reaction method.
