Piezoelectric ceramic material, application of piezoelectric ceramic material and preparation method of piezoelectric ceramic material
The invention discloses a piezoelectric ceramic material, application of the piezoelectric ceramic material and a preparation method of the piezoelectric ceramic material. The piezoelectric ceramic material disclosed by the invention is represented by a formula I: zBiScO3-yPb (Zn1/3Nb2/3) O3-xPbTiO3, in the formula I, x, y and z respectively represent the molar fractions of PbTiO3, Pb (Zn1/3Nb2/3) O3 and BiScO3, x is more than or equal to 0.58 and less than or equal to 0.64, y is more than 0 and less than or equal to 0.05, and z = 1-x-y; when the temperature is 300 DEG C, the piezoelectric charge constant d33 of the piezoelectric ceramic material is 426-655 pC/N. The piezoelectric ceramic material disclosed by the invention can be applied to piezoelectric energy collection devices in the high-temperature field, and tests show that the piezoelectric ceramic material disclosed by the invention can meet the requirements of self-powered microelectronic devices on electric energy in the ultrahigh-temperature field of 300 DEG C.
