Lead zirconate titanate thick film with molecular formula PbZr 0.52 Ti 0.42 O 3 (PZT) was prepared by a modified conventional sol-gel method through seeding and high-energy ball milling, resulting in perovskite phase formation at lower temperatures. The ball-milling time was optimized by keeping the seed particle loading (5 wt.%) constant in the sol-gel solution.
