Abrégé
(EN)
Disclosed is a piezoelectric material which comprises a multi-component composition composed mainly of lead zirconate titanate, and which contains La in an amount of 0.24 to 3.6 mol% inclusive and Co in an amount of 0.06 mol% or more, wherein the Co content is one-half the La content or less on a molar basis. The piezoelectric material can be sintered stably at a temperature as low as 950˚C or lower, and can be used for the production of a piezoelectric ceramic material having excellent piezoelectric properties.
(FR)
L'invention concerne un matériau piézoélectrique comportant une composition à plusieurs composants principalement composée de zirconate titanate de plomb, et qui contient de 0,24 à 3,6% de La en moles et au moins 0,06% de Co en moles, la teneur en Co étant la moitié de la teneur en La ou moins sur une base molaire. Le matériau piézoélectrique peut être fritté de façon stable à une température de 950°C ou moins, et peut être utilisé pour la production d'un matériau céramique piézoélectrique ayant d'excellentes propriétés piézoélectriques.
(JA)
 ジルコン酸チタン酸鉛を主成分とする多成分系組成物からなる圧電材料であって、Laを0.24モル%以上、3.6モル%以下含有し、かつ、Coを0.06モル%以上含有するが、Coの含有量はモル比でLaの二分の一以下であることを特徴とする。この圧電材料は、950°C以下という低温でも安定して焼結でき、圧電特性に優れた圧電セラミックスに製造できる。
