Summary:A method for producing a piezoelectric component is disclosed. In an embodiment, the method includes producing a ceramic precursor material of the general formula Pb1-x-y-(2a-b)/2V(2a-b)/2″BaxSry[(TizZr1-z)1-a-bWaREb]O3, where RE is a rare earth metal and V″ is a Pb vacancy, mixing the ceramic precursor material with a sintering aid, forming a stack which includes alternating layers including the ceramic precursor material and a layer including Cu and debindering and sintering the stack thereby forming the piezoelectric component having Cu electrodes and at least one piezoelectric ceramic layer including 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, and 2a>b, p≤2a−b.
