Lead-free composite piezoelectric ceramic material and preparation method thereof
The invention discloses a lead-free composite piezoelectric ceramic material and a preparation method thereof, the lead-free composite piezoelectric ceramic material is prepared by compounding a micron Mg (1-x) SrxZr0. 2Ti0. 8O3-based laminated structure piezoelectric ceramic material and a nano Na (1-y) SryCe0. 15Ti0. 85O3-based laminated structure piezoelectric ceramic material by regulating and controlling the molar ratio of micron and nano roasting powder, the pre-synthesized Mg (1-x) SrxZr0. 2Ti0. 8O3-based piezoelectric ceramic material and the pre-synthesized Na (1-y) SryCe0. 15Ti0. 85O3-based piezoelectric ceramic material are mixed according to the proportion, and then grinding, forming, sintering and polarization are sequentially carried out. The lead-free composite piezoelectric ceramic material has high piezoelectric performance and small dielectric loss, the room-temperature resistivity and density of the lead-free composite piezoelectric ceramic material are improved, and the performance of the lead-free composite piezoelectric ceramic material is more stable.
