Title (EN) VOLTAGE NON-LINEAR RESISTIVE CERAMICS
(FR) MATERIAU CERAMIQUE A RESISTANCE NON LINEAIRE DE TENSION
Abstract: front page image
(EN)Voltage non-linear resistive ceramics having large voltage non-linear coefficient as well as higher overvoltage protection capacity is produced by calcining a mixture which is composed of zinc oxide as a main ingredient and a variety of elements as minor ingredients in the form of elements or compounds. As minor ingredients of the ceramic, a predetermined amount of praseodymium, cobalt, potassium, chromium and at least one of magnesium and calcium are added, thereby providing voltage non-linear resistive ceramics having much less leakage current and increased overvoltage protection capacity.
(FR)Un materiau ceramique a resistance non lineaire de tension ayant un grand coefficient non lineaire de tension ainsi qu"une grande capacite de protection contre les surtensions est produit en calcinant un melange compose d"oxyde de zinc comme composant principal et d"une variete d"elements en tant que composants secondaires sous forme d"elements ou composes. Comme composants secondaires de la ceramique une quantite predeterminee de praseodyme, de cobalt, de potassium, de chrome et au moins de magnesium et de calcium est ajoutee, donnant ainsi un materiau ceramique a resistance non lineaire de tension ayant beaucoup moins de courant de dispersion et une capacite de protection de surtension accrue.
