Abstract: front page image
(EN)A piezoelectric ceramic contains a main component, Mn as a first auxiliary component, and a second auxiliary component containing at least one element selected from the group consisting of Cu, B, and Si. The main component contains a perovskite metal oxide having the following general formula (1): (Ba1-xCax)a(Ti1-yZry)O3 (0.100 ≤ x ≤ 0.145, 0.010 ≤ y ≤ 0.039) (1) The amount b (mol) of Mn per mole of the metal oxide is in the range of 0.0048 ≤ b ≤ 0.0400, the second auxiliary component content on a metal basis is 0.001 parts by weight or more and 4.000 parts by weight or less per 100 parts by weight of the metal oxide, and the value a of the general formula (1) is in the range of 0.9925 + b ≤ a ≤ 1.0025 + b.
(FR)La céramique piézoélectrique selon l'invention contient un composant principal, du Mn comme premier composant auxiliaire, et un second composant auxiliaire contenant au moins un élément sélectionné parmi le groupe constitué de Cu, B, et Si. Le composant principal contient un oxyde de métal du type pérovskite ayant la formule générale (1) suivante : (Ba1-xCax)a(Ti1-yZry)O3 (0,100 ≤ x ≤ 0,145, 0,010 ≤ y ≤ 0,039) (1) La quantité b (mol) de Mn par mole d'oxyde de métal est compris entre 0,0048 ≤ b ≤ 0,0400, la teneur en second composant auxiliaire sur une base de métal est supérieure ou égale à 0,001 parties en poids et inférieure ou égale à 4,000 parties en poids pour 100 parties en poids de l'oxyde de métal, et la valeur a de la formule générale (1) est comprise entre 0,9925 + b ≤ a ≤ 1,0025 + b.
