Title (EN) IMPROVED METHODS AND APPARATUS FOR THE CONTINUOUS PRODUCTION OF CARBIDES
(FR) PROCEDES ET APPAREIL AMELIORES POUR LA PRODUCTION CONTINUE DE CARBURES
Abstract: front page image
(EN)Methods and apparatus for the manufacture of silicon carbide bearing material utilizing fluidized bed techniques. Silicon-bearing material (26) and carbon-bearing material (26) are charged into a fluidized bed of electrically conductive particulate material (12) and are heated to the silicon carbide forming temperature by applying an electric potential between electrodes (16 and 24) direct contact with the particles of the fluidized bed. The silicon carbide bearing material is produced directly in a finely divided state, without further grinding.
(FR)Procedes et appareil de fabrication d'un materiau contenant du carbure de silicium utilisant des techniques a lit fluidise. Un materiau contenant du silicium (26) et un materiau contenant du carbone (26) sont charges dans un lit fluidise de materiau particulaire electriquement conducteur (12) et sont chauffes jusqu'a atteindre la temperature de formation du carbure de silicium en appliquant un potentiel electrique entre des electrodes (16, 24) qui sont en contact direct avec les particules du lit fluidise. Le materiau contenant du carbure de silicium est produit directement dans un etat finement divise sans proceder a un broyage supplementaire.
