Abstract
Piezoelectric ceramics of PZT have been developed to apply for transformers in notebook. Use of piezoelectric ceramics in applications like piezoelectric transformers was made possible by the development of new materials with high electromechanical coupling coefficients and high mechanical quality factor. "Hard" ferroelectiric ceramics of complex composition based on lead zirconate titanate with Mn additive have been prepared. The perovskitic phase reaction of the oxides. The crucial role played by the intermediate mixing and grinding procedures in the assessment of the final properties of the material was investigated. Densification up to approximately the theoretical density value was achieved. The polarization was obtained by subjecting the samples at
