Ceramic material with high and thermally stable piezoelectric properties for piezoelectric energy collection and preparation method of ceramic material
The invention discloses a ceramic material with high and thermally stable piezoelectric properties for piezoelectric energy collection and preparation, and belongs to the field of piezoelectric ceramic materials. The composition of the material is xPb (Zn1/3Nb2/3) O3-(1-x) Pb (HfyTi (1-y)) O3, x ranges from 0.05 to 0.20, and y ranges from 0.45 to 0.50. A high-temperature solid-phase reaction method is adopted for preparation, firstly, ZnO and Nb2O5 are calcined to synthesize ZnNb2O6, then other raw materials are added, and the steps of wet grinding, drying, calcination, granulation, compression molding and sintering are adopted. The piezoelectric ceramic material provided by the invention has high piezoelectric constant, excellent temperature stability and stable power generation capacity in a wide temperature range, can meet the application requirements of a piezoelectric energy collector in the wide temperature range or at a high temperature, and has remarkable social significance and application value.
