Abstract

La présente invention concerne un procédé de fabrication d'un corps fritté composite de nitrure de silicium/carbure de silicium, comprenant le mélange d’une quantité prédéterminée de poudre de nitrure de silicium avec une quantité prédéterminée de poudre de carbure de silicium, le traitement thermique de la poudre mélangée résultante à une température située entre environ 800 et 1500 °C sous une atmosphère de frittage constituée essentiellement d’azote, et la production d'un film mince de silice autour des grains individuels de nitrure de silicium et de carbure de silicium. Le film mince de silice est utile pour retarder la diffusion de l’oxygène dans les particules de nitrure de silicium et ralentir leur oxydation. La pression de l'atmosphère de frittage n'est pas sensiblement supérieure à la pression atmosphérique.
