Lead-free piezoelectric ceramic material with high electromechanical coupling coefficient as well as preparation method and application of lead-free piezoelectric ceramic material
The invention relates to the technical field of piezoelectric ceramic materials, in particular to a lead-free piezoelectric ceramic material with a high electromechanical coupling coefficient as well as a preparation method and application of the lead-free piezoelectric ceramic material. The lead-free piezoelectric ceramic material with the high electromechanical coupling coefficient is prepared from the following substrates: (0.99-x) (K < 0.5 > Na < 0.5 >) (N < b > < 0.96 > Sb < 0.04 >) O < 3-0.01 > BaZrO < 3-x > Bi < 0.5 > (Ag < 0.5 > Li < 0.5 >) < 0.5 > HfO < 3 >. The lead-free piezoelectric ceramic material with the high electromechanical coupling coefficient has excellent electrical properties, KP of the lead-free piezoelectric ceramic material can reach 57%, d33 of the lead-free piezoelectric ceramic material can reach 462 pC/N, and therefore the lead-free piezoelectric ceramic material can be applied to the industry. The preparation process of the lead-free piezoelectric ceramic material with the high electromechanical coupling coefficient is safer, and the lead-free piezoelectric ceramic material does not contain toxic substances such as lead element and methylbenzene.
