摘要

The invention relates to piezoelectric ceramic materials based on the system Pb(Zr,Ti)O₃, i.e. solid solutions of lead zirconate PbTO₃, characterized by having very good dielectric and electromechanical properties that can be adopted for different uses by modifying the composition. The piezoelectric ceramic materials based on the system Pb(Zr,Ti)O₃are modified in order to obtain a high level of piezoelectric activity. The invention provides piezoelectric ceramic materials based on lead zirconate titanate (PZT) having the crystal structure of perovskite with formula A²⁺B⁴⁺O₃²⁻, which are characterized by a substitution of heterovalent acceptor and donator ions at Zr/Ti sites.
