摘要：
A ceramic material having the general formula (BiXNayM zLuM V w) (Ti1-sZs)03, where: M comprises at least one element of main group 1, M comprises at least one element of main group 2, L comprises at least one element of the lanthanides, V is a vacancy and Z is selected from among Zr, Hf and combinations thereof, is provided. Furthermore, a piezoelectric actuator comprising the ceramic material and a process for producing the ceramic material are provided.
