In this paper, in order to develop optimum composition ceramics with excellent piezoelectric properties, $(Na_{0.525}K_{0.443}Li_{0.037})(Nb_{0.823}Sb_{0.08}Ta_{0.037})O_3+0.3wt%Bi_2O_3+0.4wt%Fe_2O_3$ lead-free piezoelectric ceramics were synthesized by conventional soild-state method. The calcination temperature of columbite precursors were fabricated at temperature range from $950^{\circ}C$ to $1,150^{\circ}C$ and sintering aids with low melting point were added to densify these ceramics. Effect of calcination temperature on dielectric and piezoelectric properties of ceramics were investigated. the ceramics with B-site columbite precursors at temperature of $1,100^{\circ}C$ obtained the optimal values of $d_{33}=272$ [pC/N], $k_p=0.51$, $Q_m=102$, ${\varepsilon}_r=978$.
