Tantalum oxide-doped hafnium calcium barium titanate large-dielectric-constant lead-free piezoelectric ceramic and preparation method thereof
The invention belongs to the technical field of material science, and particularly discloses tantalum oxide doped hafnium calcium barium titanate large-dielectric-constant lead-free piezoelectric ceramic, the component of which is Ba < 0.85 > Ca < 0.15 > Ti < 0.9 > Hf < 0.1 > O < 3 + x > Ta2O5. According to the invention, the dielectric property of the lead-free piezoelectric ceramic is improved, so that the lead-free piezoelectric ceramic can be applied to electronic components such as piezoelectric ceramic capacitors and piezoelectric transducers, and the application range of the lead-free piezoelectric ceramic is widened. A novel large-dielectric-constant lead-free piezoelectric ceramic system is invented by improving the sintering problem and the element concentration; the preparation method of the material is easy to popularize and apply, and the material can be applied to electronic components such as piezoelectric ceramic capacitors and piezoelectric transducers.
