(FR) PROCÉDÉ DE SYNTHÈSE D'UN NITRURE DE MÉTAL DE TRANSITION ET NITRURE DE MÉTAL DE TRANSITION
Abstract
(EN)
The present invention discloses a method of synthesizing transition metal nitride by using supercritical ammonia. Transition metal nitride such as vanadium nitride, molybdenum nitride, titanium nitride, nickel nitride, neodymium nitride, iron nitride, etc. can be synthesized in supercritical ammonia with reducing mineralizers such as potassium, sodium, lithium, magnesium, calcium, and aluminum. Since supercritical ammonia has characteristics of both gas and liquid, it can cover complicated fine structure or fine particles. The new method is suitable for forming a protective coating on complicated structure or forming micro- to nano-sized particles.

(FR)
La présente invention concerne un procédé de synthèse d'un nitrure de métal de transition par l'utilisation de l'ammoniac supercritique. Du nitrure de métal de transition comme le nitrure de vanadium, le nitrure de molybdène, le nitrure de titane, le nitrure de nickel, le nitrure de néodyme, le nitrure de fer, etc. peuvent être synthétisés dans l'ammoniac supercritique avec des minéralisateurs réducteurs comme le potassium, le sodium, le lithium, le magnésium, le calcium, et l'aluminium. Etant donné que l'ammoniac supercritique présente des caractéristiques à la fois du gaz et du liquide, il peut couvrir une structure fine ou des particules fines compliquées. Le nouveau procédé convient pour la formation d'un revêtement protecteur sur une structure compliquée ou la formation de particules micronisées à nanonisées.
