In this paper, in order to develop Pb-free piezoelectric ceramics, (Li_(0.04)Na_(0.44)K_(0.52)) (Nb_(0.86Ta_(0.10Sb_(0.04))O_(3) 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 d_(33)=254 at calcination temperaure of 800℃ and sintering temperature of 1110℃.
