Abstract

La présente invention concerne des nanoparticules d'alliages intermétalliques, tels que FeAl, Fe¿3?Al, NiAl, TiAl et FeCoV, qui présentent une grande variété d'applications dans le domaine structural, magnétique, catalytique, résistif, électronique et de codage par codes à barres. Les poudres nanométriques peuvent être utilisées afin de produire des parties structurales présentant des propriétés mécaniques améliorées, des parties magnétiques présentant une saturation magnétique améliorée, des matériaux de catalyse présentant une activité catalytique améliorée, des éléments de circuit à couche mince présentant une résolution améliorée et des images sérigraphiées, telles que des codes à barres magnétiques, présentant des propriétés magnétiques améliorées. Contrairement aux matériaux à base de FeAl en vrac, qui ne sont pas magnétiques à température ambiante, les nanoparticules selon cette invention présentent des propriétés magnétiques à température ambiante.
