Abstract
A method of making a fine powder of a metal and another element in an intimate mutual relation such as an alloy or a chemical compound of a metal and a non metallic element, wherein a gaseous mixture of the metal and the other element is passed through a convergent-divergent nozzle and is thereby rapidly cooled by adiabatic expansion so that the metal and the other element react with each other while the resulting alloy or chemical compound is solidified to form fine particles.
