Abstract

An inventive method is provided for synthesizing an intermetallic compound. According to exemplary inventive practice, two metallic elements are weighed out in quantities corresponding to their molecular weights in an intermetallic compound of interest. The two metallic elements are mixed together to produce a metallic mixture in powder form. According to many inventive embodiments, a ball-mill device is implemented to thoroughly or intimately mix the two metallic elements into a fine powder. The powdered metallic mixture is exothermically reacted to produce an at least substantially pure intermetallic compound in powder form. According to many inventive embodiments, the exothermic reaction is brought about in a vacuous or inert-gaseous (e.g., helium) environment through electrification of a tungsten wire filament that is completely embedded in the powdered metallic mixture.
