1. a lead-free piezoceramic material, it has chemical general formula:

  • xBiCoO 3-y(Bi 0.5Na 0.5)TiO 3-z(Bi 0.5K 0.5)TiO 3

    xBiCoO 3-y(Bi 0.5Na 0.5)TiO 3-zNaNbO 3

    xBiCoO 3-y(Bi 0.5Na 0.5)TiO 3-zKNbO 3

    xBiCoO 3-yBi(Mg 0.5Ti 0.5)O 3-z(Bi 0.5Na 0.5)TiO 3

    XBiCoO 3-yBaTiO 3-z (Bi 0.5na 0.5) TiO 3;

    Or xBiCoO 3-yNaNbO 3-zKNbO 3

    Wherein x+y+z=1, and x, y, z ≠

    0.
