<p>The purpose of the present invention is to reduce an operation electric field and improve a field induced variation property by manufacturing ceramic having one crystalline direction by a reactive templated grain growth (RTGG) method. According to the present invention, the method for manufacturing leadless piezoelectric ceramic by an RTGG method manufactures Bi-based leadless piezoelectric ceramic by using BNT-BKT-BA powder and NBiT particles.
