A piezoceramic composition of a calculated empirical formula Pb1-aREbAEc[ZrxTiy(NinMom)z]O3, wherein RE represents a rare earth metal having a rare earth metal content b, AE represents an alkaline earth metal having an alkaline earth metal content c, nickel is provided with a nickel content n.z, and molybdenum is provided with a molybdenum content m.z. Furthermore, the following correlations apply : a0; m>0; 0.1=n/m=5; x>0; y>0; z>0, and x+y+z=1. In a method for producing a piezoceramic component a) a green ceramic member containing the piezoceramic composition is supplied; and b) the green member is subjected to a thermal treatment such that the piezoceramic material of the component is produced from the piezoceramic composition. The thermal treatment encompasses calcining and/or sintering of the piezoceramic composition. The piezoceramic composition is compressed below 1000° C., thus allowing metals melting at a lower temperature to be sintered along with the piezoceramic composition.
