摘要:
A lead-free piezoelectric ceramic material has the general chemical formula xBiCoO3-y(Bi0.5Na0.5)TiO3-z(Bi0.5K0.5)TiO3, xBiCoO3-y(Bi0.5Na0.5)TiO3-zNaN-bO3, xBiCoO3-y(Bi0.5Na0.5)TiO3-zKNbO3, xBiCoO3-yBi(Mg0.5Ti0.5)O3-z(Bi0.5Na0.5)TiO3, xBiCoO3-yBa-TiO3-z(Bi0.5Na0.5)TiO3, or xBiCoO3-yNaNbO3-zKNbO3; wherein x+y+z=1, and x, y, z≠0.
