Abstract

SELON LA PRESENTE INVENTION, LE NITRURE DE SILICIUM (SIN) INOXYDABLE EST OBTENU A PARTIR D'UN MELANGE CONTENANT ENTRE 2 ET 4 EN POIDS D'OXYDE DE SILICIUM (SIO), MOINS DE 0,1 EN POIDS D'OXYDE DE SILICIUM (SIO), MOINS DE 0,1 EN POIDS D'IMPURETES CATIONIQUES ET UNE QUANTITE CRITIQUE D'OXYDE D'YTTRIUM. CETTE QUANTITE D'OXYDE D'YTTRIUM EST, DE PREFERENCE, COMPRISE ENTRE 11 ET 13 EN POIDS. APPLICATION: AUX PIECES DE MOTEURS OU DES RECUPERATEURS DE CHALEUR, SOUMISES A DES TEMPERATURES ELEVEES.ACCORDING TO THE PRESENT INVENTION, STAINLESS SILICON NITRIDE (INS) IS OBTAINED FROM A MIXTURE CONTAINING BETWEEN 2 AND 4 BY WEIGHT OF SILICON OXIDE (SIO), LESS THAN 0.1 BY WEIGHT OF SILICON OXIDE ( WIS), LESS THAN 0.1 BY WEIGHT OF CATIONIC IMPURITIES AND A CRITICAL AMOUNT OF YTTRIUM OXIDE. THIS QUANTITY OF YTTRIUM OXIDE IS PREFERREDLY BETWEEN 11 AND 13 BY WEIGHT. APPLICATION: TO ENGINE PARTS OR HEAT RECOVERERS SUBJECT TO HIGH TEMPERATURES.
