The present invention relates to a ternary lead-free piezoelectric ceramic composition with a high strain rate, which has a perovskite crystal structure, and substitutes CaTiO_3 for a part of (Bi,Na)TiO_3 in a (Bi,Na)TiO_3-SrTiO_3-based solid solution having SrTiO_3 added thereto by using (Bi,Na)TiO_3 containing Bi, Na, Ti, and O as a parent body. In addition, the ternary lead-free piezoelectric ceramic composition with a high strain rate of the present invention has a perovskite crystal structure, and substitutes BiAlO_3 for a part of (Bi,Na)TiO_3 in a (Bi,Na)TiO_3-SrTiO_3-based solid solution having SrTiO_3 added thereto by using (Bi,Na)TiO_3 which contains Bi, Na, Ti, and O as a main component, as a parent body. COPYRIGHT KIPO 2019 (AA) Start (BB) End (S100) Step of mixing oxide powder of Bi, Na, Sr, Ti, and Ca (S110) Step of calcining the mixed powder (S120) Step of performing wet-grinding for the calcined power, and pressing the same to form a molded article (S130) Step of sintering ...
