Abstract

On décrit un four adapté à l'agrandissement à l'échelle des processus à transfert thermique limité réalisés à des températures élevées, tels que la réduction carbo-thermique des oxydes d'éléments de transition ou des terres rares. Le four est chauffé à haute fréquence par des bobines isolées externes (3), et l'on place le suscepteur (2), de préférence des anneaux de graphite, à l'intérieur de la charge (1) et à distance des surfaces externes de celle-ci. En conséquence, la chaleur est transférée à la charge (1) de manière tridimensionnelle et le processus touche à sa fin avant que l'isolation (4) ne soit soumise à des températures élevées. Grâce à ce transfert de chaleur tridimensionnel, on peut réaliser des fours plus grands conformes aux limitations du transfert de chaleur de ces processus à température élevée, et l'on peut obtenir des rendements plus élevés.
