In this paper, in order to develop Pb-free piezoelectric ceramics, (Li0.04Na0.44K0.52)(Nb0.86Ta0.10Sb0.04)O3 ceramics were fabricated with the variation of calcination temperature and sintering temperature. Specimens couldn``t be sintered below 1110 ℃ and showed the largest density at calcination temperature of 800 ℃. Specimens manufactured with the variation of calcination temperature showed pseudo-tetragonal phase, and showed the optimal values of kp=0.45, εr=1336 and d33=254 at calcination temperature of 800 ℃ and sintering temperature of 1110 ℃.
