Temperature-stable perovskite structure high-temperature piezoelectric ceramic material and preparation method thereof
The invention discloses a temperature-stable perovskite structure high-temperature piezoelectric ceramic material and a preparation method thereof, and belongs to the field of piezoelectric ceramic materials. The chemical composition of a matrix of the ceramic material is xBi (Zn2/3Nb1/3) O3-yBiScO3-zPbTiO3 (x is more than or equal to 0.003 and less than or equal to 0.01, y is more than or equal to 0.35 and less than or equal to 0.425, and z is equal to 1-x-y), and the ceramic material is prepared by adopting a high-temperature solid-phase reaction method. The high-temperature piezoelectric ceramic material provided by the invention has high Curie temperature, and has high and stable piezoelectric charge coefficient, piezoelectric voltage coefficient and transduction coefficient in a wide temperature range of 50-260 DEG C. Advanced electromechanical coupling devices such as piezoelectric sensors and piezoelectric energy collectors which have higher requirements on comprehensive piezoelectric parameters of materials and are applied to the high-temperature field can be met, and the method has great engineering application value.
