Abstract Piezoelectric ceramics are a kind of electronic ceramic materials with piezoelectric characteristics, which widely used in various fields because their unique electromechanical conversion characteristics. The Curie temperature (TC) and constant (d33) increased to ensure that the have good performance at higher operating temperatures. In this study, (1-x)(K0.5Na0.5)(Nb0.95Ta0.05)O3-x(Bi0.5Na0.5)(Zr0.5Ti0.5)O3 were prepared by traditional solid phase sintering process. By controlling...
Abstract In this study, (1‐ x )Bi 0.5 Na 0.46 Li 0.04 TiO 3 ‐ Bi 0.9 Sm 0.1 ScO (BNLT‐ BSS) relaxation ferroelectric ceramics were successfully prepared by conventional solid phase method. Multiscale analyses such as XRD and EDS confirmed that these form a solution with single‐phase perovskite structure. As the doping amount of increases, smaller grain size is obtained at = 0.1, breakdown strength increases to 350 kV/cm, resulting in higher W rec 5.92 J/cm , η 82.2%. addition, demonstrate...
The surface oxidation of chalcopyrite in solutions pH 9.2 and 12.7 has been investigated using electrochemical techniques, X‐ray photoelectron spectroscopy, Auger electron spectroscopy. results show that the process consists essentially three potential‐ pH‐dependent stages. In (pH 9.2), on increasing electrode potential from −0.6 to +0.02 V vs. SCE, iron top layer is oxidized, forming a monolayer . copper sulfur remain unoxidized as phase we designate , which together with forms film...
