Structural and electrical properties of Zr-doped K0.48Na0.52NbO3 ceramics: “Hard” lead-free piezoelectric
Beltrán Mir, Héctor; Vendrell, Xavier; Dos Santos Veiga, Emerson Luiz; Mestres, Lourdes; Cordoncillo, Eloisa Elsevier (2023-10)The structural and electrical properties of K0.48Na0.52Nb1−xZrxO3−δ (x = 0–0.04) ceramics prepared by the conventional solid-state reaction method were studied. Pellets with composition x ≤ 0.03 sintered at 1125 °C for 2 ... -
Understanding the rapid reoxidation process and the electrical properties of Spark Plasma sintered pyrochlores
Dos Santos Veiga, Emerson Luiz; Beltrán Mir, Héctor; Fourcade, Stéphane; Chung, U-Chan; MICHAU, Dominique; Elissalde, Catherine; Mauvy, Fabrice (2024-02-07)Pyrochlore structures with composition Pr2−xSmxZr2O7 (x = 0, 1, and 2) were synthetized and studied. Spark Plasma Sintering (SPS) was employed to produce ceramics with over 95% of relative density. The reoxidation behavior ...
