Abstract

L'invention concerne les tubes à vide, et notamment les tubes électroniques. Pour réaliser le tube, et notamment un collecteur d'électrons à plusieurs électrodes (30, 40, 50, 60), on réalise les électrodes sous forme de blocs de céramique à forte conductivité thermique. Les blocs sont superficiellement (au moins) conducteurs de l'électricité. Ils sont de préférence en céramique isolante telle que du nitrure d'aluminium, et sont rendus conducteurs sur une partie de leur surface. La partie superficielle conductrice est de préférence constituée par une céramique conductrice, de préférence à base de nitrure de titane, ou de matériaux céramiques conducteurs similaires. On gagne ainsi en solidité, en capacité d'évacuation de chaleur, et en poids.
