High-density fine-grain piezoelectric ceramic applied to high-power device and preparation method of high-density fine-grain piezoelectric ceramic
The invention discloses a high-density fine-grain piezoelectric ceramic applied to a high-power device and a preparation method thereof, and belongs to the technical field of piezoelectric ceramics. The chemical composition is as follows: Pb < 0.9 > Ba < 0.1 > Zr < 0.53 > Ti < 0.47 > O < 3-x > wt.% MnCO3, 0.2 lt, xlt; and 0.6. Raw materials Pb3O4, BaCO3, TiO2, ZrO2 and MnCO3 are adopted, and ball milling and calcination are performed to obtain the Pb3O4-BaCO3-TiO2-MnCO3 composite material. The high-density fine-grain piezoelectric ceramic meeting the high-power requirement is obtained through a comprehensive method of A-site and B-site co-doping and ceramic density regulation and control.
