Piezoceramic material and preparation method thereof
The invention discloses a piezoelectric ceramic material and a preparation method thereof, and relates to the field of ceramic materials. The piezoelectric ceramic material comprises lead oxide, manganese dioxide, niobium pentoxide, antimony trioxide, zirconium dioxide and titanium dioxide, and the chemical formula of the piezoelectric ceramic material is (PbO). (MnO2) 0.08/3 (Nb2O5) 0.04/3 (Sb2O3) 0.04/3 (ZrO2) 0.828. (TiO2) 0.092. The preparation method of the piezoelectric ceramic material comprises the following steps: weighing, carrying out primary ball milling, drying, pre-sintering, carrying out secondary ball milling, granulating, drying, carrying out dry pressing molding, discharging glue and sintering, coating with silver, and polarizing. The problems that an existing piezoelectric ceramic material is low in relative dielectric constant and high in dielectric loss are solved. The method is widely applied to the field of surface acoustic wave device preparation.
