Abstract: front page image
(EN)Provided is a piezoelectric material which has satisfactory insulation property and piezoelectric property and which does not contain lead and potassium. The piezoelectric material includes a perovskite-type metal oxide that is represented by the following general formula: (NaxBa1-y) (NbyTi1-y) O3, where relationships of 0.80≤x≤0.95 and 0.85≤y≤0.95 are satisfied, and y x 0.05 mol% or more to y x 2 mol% or less of copper with respect to 1 mol of the perovskite-type metal oxide.
(FR)Cette invention concerne un matériau piézoélectrique qui possède des propriétés isolantes et des propriétés piézoélectriques suffisantes et qui ne contient pas de plomb ni de potassium. Ce matériau piézoélectrique contient un oxyde de métal de type pérovskite représenté par la formule générale suivante: (NaxBa1-y) (NbyTi1-y) O3, dans laquelle les inéquations 0,80≤x≤0,95 et 0,85≤y≤0,95 sont satisfaites, avec y x 0,05% mol ou plus à y x 2% mol ou moins de cuivre par rapport à 1 mol de l'oxyde de métal de type pérovskite.
