Abstract
A ceramic material includes first and second ceramic materials. The first ceramic material has a perovskite structure and defines a host lattice. The first ceramic material contains lead, zirconium and titanium, e.g., lead zirconate titanate. The second ceramic material has a cryolite structure. The ceramic material may be part of a piezo-actuator containing ceramic layers formed of the ceramic material.
