ABSTRACT Substitution in A or/and B sites of the perovskite lattice, or strain engineering is known to influence the properties of piezoelectric ceramics. Cerium (Ce) has been identified as a substituent to investigate the properties of lead-free (Ba0.85Ca0.15)(Zr0.1Ti0.9)O3 (BCZT) ceramics. Structural, ferroelectric, piezoelectric and dielectric properties of Ce substituted BCZT ceramics were investigated systematically and were correlated with the strain induced structural phase transition. Ce substituted for Ti in BCZT ceramics showed coexistence and larger phase fractions of tetragonal and rhombohedral phases and exhibited enhanced piezoelectric and dielectric responses, d33 ∼703 pC/N, g33 ∼16 mV.m/N, kp ∼61% and Tc ∼ 123°C.

晶格应变对无铅(Ba0.85Ca0.15)(Zr0.1Ti0.9)O3陶瓷相变和压电性能的影响

摘要 钙钛矿晶格的 A 或/和 B 位的取代或应变工程已知会影响压电陶瓷的性能。铈 (Ce) 已被确定为研究无铅 (Ba0.85Ca0.15)(Zr0.1Ti0.9)O3 (BCZT) 陶瓷性能的取代基。系统地研究了 Ce 取代的 BCZT 陶瓷的结构、铁电、压电和介电性能，并与应变引起的结构相变相关联。在 BCZT 陶瓷中用 Ce 代替 Ti 显示出四方相和菱面体相的共存和更大的相分数，并表现出增强的压电和介电响应，d33 ∼703 pC/N、g33 ∼16 mV.m/N、kp ∼61% 和 Tc ∼123 ℃。图形概要
