PIEZOELECTRIC CERAMIC COMPOSITION |
摘要 |
Disclosed is a piezoelectric ceramic composition which is produced by adding two or more metal elements and has excellent piezoelectric properties. The piezoelectric composition comprises the main ingredient represented by the general formula: [Lix(K1-yNay)1-x](Nb1-z-wTaZSbw)O3 (0<=x<=0.2, 0<=y<=1, 0<=z<=0.4, 0<w<=0.2) and the auxiliary ingredient represented by the general formula: ABO3 (wherein A and B independently represent a metal element having a valence of +3 or together represent a combination of at least two metal elements each having a valence of +3 in average; and ABO3 represents a compound having a perovskite structure).
