Abstract

Installation dont l'alimentation en courant s'effectue au moyen d'électrodes, à travers un noyau de résistance en matière contenant du carbone, qui est logé horizontalement dans le lit de fusion constitué par un mélange de coke granuleux, de sable quartzeux et de produits d'addition. Les électrodes sont disposées l'une à côté de l'autre et le rapport de la demi-longueur du noyau de résistance à l'espacement des électrodes est au moins égal à 0,8. L'invention trouve application en particulier à la production de carbure de silicium, à partir de dioxyde de silicium et de carbone.
