摘要
The present disclosure relates to a method for obtaining lead-free piezoelectric materials, including: Step S100, adjusting the T/O phase boundary of a first lead-free piezoelectric material: for the first lead-free piezoelectric material, adjusting the T/O phase boundary between the tetragonal phase T and the orthorhombic phase O to be near the room temperature by doping; Step S200, further adjusting the C/T phase boundary and the O/R phase boundary: further adjusting the C/T phase boundary between the cubic paraelectric phase C and the tetragonal phase T, and the O/R phase boundary between the orthorhombic phase O and the rhombohedral phase R by doping, so as to enable the C/T phase boundary and the O/R phase boundary to approach the T/O phase boundary; and Step S300, obtaining second lead-free piezoelectric materials: obtaining multiple second lead-free piezoelectric materials with different piezoelectric constants d33 and different Curie temperatures TC in the process.
