Abstract

ON OPERE PAR PRESSAGE ISOSTATIQUE DE POUDRE DE NITRURE DE SILICIUM QUI CONTIENT DU SILICIUM LIBRE OU D'UN PRODUIT PRE-FORME A PARTIR DE CETTE POUDRE, A LA TEMPERATURE DE FRITTAGE DU NITRURE DE SILICIUM. LES INTERVALLES EXISTANT ENTRE LES PARTICULES DE LA POUDRE OU LES PORES DU PRODUIT PRE-FORME 10 SONT REMPLIS D'AZOTE JUSQU'A UNE QUANTITE QUI PEUT SE COMBINER AVEC LE SILICIUM CONTENU DANS LE NITRURE DE SILICIUM, ET LA POUDRE OU LE PRODUIT PRE-FORME EST TRAITE THERMIQUEMENT, EN VUE DE LA COMBINAISON DE L'AZOTE ET DU SILICIUM POUR FORMER DU NITRURE DE SILICIUM, ET EST SOUMIS AU PRESSAGE ISOSTATIQUE A LA TEMPERATURE DE FRITTAGE. ON OBTIENT DES OBJETS QUI PRESENTENT UNE RESISTANCE NETTEMENT PLUS ELEVEE AUX HAUTES TEMPERATURES QUE DES OBJETS QUI ETAIENT FABRIQUES A PARTIR DE NITRURE DE SILICIUM D'APRES DES METHODES ANTERIEUREMENT CONNUES.
