Abstract: A composition includes at least one Pb/Ni/Nb - Pb/Mg/W - Pb/Zr/Ti mixed oxide. A piezoelectric device may be made by providing at least two layers comprising the composition and coated with an outer electrode material; providing a plurality of layers comprising the composition and coated with an inner electrode material; combining or stacking a plurality of layers coated with inner electrode materials between two outer electrodes; and sintering or co-firing the inner electrode materials and outer electrode materials at a temperature at or below about 1000° C.
