Relaxation ferroelectric ceramic with high field-induced strain temperature stability and preparation method thereof
The invention belongs to the technical field of ferroelectric ceramic materials, and discloses relaxation ferroelectric ceramic with high field-induced strain temperature stability and a preparation method thereof. The chemical composition of the relaxation ferroelectric ceramic with high field-induced strain temperature stability is Pb 0.955 Sm0.03 [(Mg 1/3 Nb 2/3 )1-x Ti x ]O3, wherein x is greater than or equal to 0.32 and less than or equal to 0.35. The invention also discloses a preparation method of the relaxation ferroelectric ceramic with high field-induced strain temperature stability. The ferroelectric ceramic disclosed by the invention not only has high field-induced strain in a temperature range of-10 DEG C to + 65 DEG C, but also has excellent field-induced strain temperature stability. According to the relaxation ferroelectric ceramic with the high field-induced strain temperature stability, the change rate of the transverse field-induced strain along with the temperature at the temperature ranging from-10 DEG C to + 65 DEG C is smaller than +/-5%, and the requirement of a high-precision micro-displacement actuator for the field-induced strain temperature stability is met.
