A problem of fabricating piezoelectric tape ceramic was poor for density after sintering. Three-step sintering (3SS) techniques were prepared to obtain tape casting ceramic with density and piezoelectric properties better than conventional sintering (CS). Pb0.976K0.012 Bi0.012[(Zr0.53 Ti0.47)0.99 Nb0.01]O3 ceramic was synthesized using tape casting accompanied with sintering techniques. The green tapes were sintered on three steps temperature that is 870, 970, and 1070 °C, respectively, and compared with two steps over a wide sintering temperature range of 870, and 1050 °C, respectively. The optimum density, dielectric properties, polarization electric field loop, piezoelectric coefficient (d33), and mechanical coupling (kp) were attained by three step sintering. The enhanced remanent polarization of 40 μC cm^–1 and d33 value of 220 – 280 pC N^–1. In addition, kp was enhanced of 0.45 be able to obtain for the tape ceramic.
