Abstract Bi(Li0.5Nb0.5)O3 (BLN) was adopted to tailor the Curie temperature (TC) and the resulting ferroelectric and electrostrictive properties of solid solutions of the morphotropic phase boundary relaxor ferroelectric 0.67 Pb(Mg1/3Nb2/3)O3-0.33PbTiO3 (0.67PMN-0.33 PT). The ceramic samples were synthesized by a solid reaction method, and the BLN content was set to 2.5 at.%, 5 at.%, 7.5 at.%, and 10 at.%. X-ray diffraction results suggested that BLN cannot enter the 0.67PMN-0.33 PT crystal lattice completely, resulting in the formation of a second phase (Pb2Ti2O6 with pyrochlore structure) in all the samples. With increasing BLN content, a decrease in TC and a ferroelectric-to-relaxor transition were revealed by the dielectric and ferroelectric properties. High electric-field-induced strains of 0.167%–0.228% with low hysteresis (
