Antimony-modified K0.48Li0.02Na0.5NbO3 (KLNN) piezoelectric ceramics were prepared via a microwave sintering process. The effect of antimony-substitution amount (i.e., x=0, 0.02, 0.04, 0.06, 0.08) on the microstructure, surface topography, piezoelectric and ferroelectric characteristics were investigated. The perovskite single phase structure is confirmed in the entire substitution range, together with good crystallization and even grains. Antimony can form a uniform solid solution in KLNN lattice, improving the microstructure and piezoelectric and ferroelectric characteristics of KLNN-based piezoelectric ceramics. The Curie temperature dielectric constant peak (εr), unidirectional strain (ε) and piezoelectric coefficient (d33) of Na0.5K0.48Li0.02(Nb0.94Sb0.06)O3 ceramic all reach the maximum value, which are εr=5 557, ε=0.08%, d33=208 pC/N.
