Abstract

Corps en titanate de strontium semi-conducteur dopé à l'aide d'oxyde de niobium ou d'oxyde de tantale et de 0,1 à 2 % en poids de SiO2 et éventuellement, 0,1 à 2 % en poids de Al2 O3 . Après diffusion d'un mélange d'oxydes métalliques constituant une couche isolante aux limites des grains et l'application d'électrodes on obtient un condensateur à couche d'arrêt.
