Abstract
L'invention concerne un procédé de fabrication de corps de carbure de silicium lié par réaction. Le procédé comprend le chauffage sous vide ou en atmosphère inerte, au moins à la température de fusion du silicium élémentaire, d'une ébauche poreuse contenant essentiellement un mélange uniforme de carbure de silicium et de carbone, alors qu'une ébauche formée par un mélange de silicium élémentaire et d'une petite quantité de carbone finement divisé, formant une ébauche est placée au contact de la première ébauche. Lors du chauffage, une partie du silicium élémentaire réagit avec le carbone et forme un liant poreux et friable de carbure de silicium qui guide le reste du silicium élémentaire dans la première ébauche poreuse, le silicium réagissant alors avec le carbone et formant une quantité supplementaire de carbure de silicium. Application à la fabrication de bagues d'étanchéité de carbure de silicium.
