Abstract

Un alliage céramique adhésif capable d'adhérer à un matériau céramique d'un oxyde, d'un carbure, d'un nitrure, d'un borure ou d'un mélange de ceux-ci, avec un angle de contact de 0o, comprend essentiellement du Si et un ou plusieurs éléments choisis dans les éléments du groupe Ti et V, Y et Ca. La proportion de Si par rapport à la totalité des éléments des groupes Ti et V, Y, et Ca (en poids) est de (5 - 95): (100 - quantité de Si), la somme de Si et des éléments des groupes Ti et V, Y, et Ca étant d'au moins 60% en poids, sur la base du poids total de l'alliage. Cet alliage peut être utilisé pour métalliser des matériaux céramiques, pour cimenter des métaux à des céramiques ou pour cimenter ensemble des matéraiux céramiques, ou comme métal pour la phase liante d'un cermet.
