Abstract:
(EN) The present invention relates to a method for synthesizing aluminum nitride at a low temperature and, more specifically, to a method for synthesizing aluminum nitride, comprising: preparing a porous body by heating and debinding, under a nitrogen gas atmosphere at atmospheric pressure, feedstock granules or a molded product prepared therefrom, the feedstock granules being prepared by pressure mixing a mixture powder, which comprises 0.5-8 wt% of a zinc powder, 0.01-2 wt% of a magnesium powder, 0.01-1 wt% of a silicon powder, 0.01-1 wt% of a copper powder and the balance of an aluminum powder, with an organic binder; and causing a rapid nitridation reaction of an aluminum powder. In addition, the present invention relates to a method for synthesizing a composite phase material having a high aluminum nitride content by further adding, to the aluminum mixture powder, one or more inorganic materials selected from the group consisting of lithium, calcium, phosphorus, gadolinium, iron, nickel, cobalt, manganese, silver, chromium, zirconium, strontium, molybdenum, tungsten and an alloy thereof, or Al2O3, SiO2, ZrO2, CaO, Y2O3, TiC, TiN, B4C, SiC, Si3N4, TiB2, h-BN, c-BN, diamond, a carbon nanotube and graphene, and sintering the same under the nitrogen gas atmosphere.
(FR) La présente invention concerne un procédé de synthèse de nitrure d'aluminium à basse température et, plus particulièrement, un procédé de synthèse de nitrure d'aluminium, consistant à : préparer un corps poreux par chauffage et déliantage, dans une atmosphère d'azote gazeux à pression atmosphérique, de granulés de matière première ou d'un produit moulé préparé à partir de ceux-ci, les granulés de matière première étant préparés par mélange sous pression d'une poudre de mélange, qui comprend 0,5-8 % en poids d'une poudre de zinc, 0,01-2 % en poids d'une poudre de magnésium, 0,01-1 % en poids d'une poudre de silicium, 0,01-1 % en poids d'une poudre de cuivre et le reste étant une poudre d'aluminium, avec un liant organique ; et provoquer une réaction de nitruration rapide d'une poudre d'aluminium. De plus, la présente invention concerne un procédé de synthèse d'un matériau à phase composite, présentant une teneur élevée en nitrure d'aluminium par l'addition supplémentaire, à la poudre de mélange d'aluminium, d'un ou de plusieurs matériaux inorganiques choisis dans le groupe constitué par le lithium, le calcium, le phosphore, le gadolinium, le fer, le nickel, le cobalt, le manganèse, l'argent, le chrome, le zirconium, le strontium, le molybdène, le tungstène et un alliage correspondant ou Al2O3, SiO2, ZrO2, CaO, Y2O3, TiC, TiN, B4C, SiC, Si3N4, TiB2, h-BN, c-BN, le diamant, un nanotube de carbone et le graphène et son frittage sous l'atmosphère d'azote gazeux.
