Abstract

Un procédé d'obtention de nitrures consiste à utiliser, comme matière première, des alliages à base de fer ou d'acier (ou bien leur déchets), contenant des éléments formant des nitrures. Le procédé consiste à nitrurer ladite matière première sous une pression d'azote comprise entre 15 et 200 MPa à une température comprise entre 800 et 1400 °C, à dissoudre le produit de nitruration dans de l'acide chlorhydrique et à séparer les sédiments. Les températures les plus basses du processus de nitruration ne dépassant pas 1200 °C permettent d'obtenir des poudres en fine dispersion, et les températures les plus élevées permettent d'obtenir des grosses cristallites. Un sous-produit résultant de ce procédé est le chlorure de fer qui est utilisable, ce procédé est donc practiquement sans déchets.
