Abstract

Ce procédé est caractérisé en ce qu'on effectue le traitement thermique de silanes azotés en présence d'ammoniac. Le nitrure est caractérisé en ce qu'il a une teneur en chlore inférieure à 0,05 % en poids et une teneur en azote supérieure à 38 % en poids. L'invention trouve une application avantageuse dans le domaine des matériaux céramiques, notamment pour turbines à gaz.
