A piezoelectric component has at least one piezoelectric ceramic layer and at least one electrode adjacent the piezoelectric ceramic layer. The piezoelectric ceramic layer has a piezoelectric ceramic material of the general formula Pb1-x-y-[(2a-b)/2]-p/2V[(2a-b)/2-p/2]″CupBaxSry[(TizZr1-z)1-a-bWaREb]O3, where 0≦x≦0.035, 0≦y≦0.025, 0.42≦z≦0.5, 0.0045≦a≦0.009, 0.009≦b≦0.011, 2a>b, p≦2a−b, RE is a rare earth metal, and V″ is a Pb vacancy. |
