Abstract

Process for manufacturing refractory metals, endowed with a high chemical reactivity, in particular in the presence of oxygen and nitrogen, such as zirconium and hafnium, characterized by the combination of the following successive phases: - the oxides of the metals mentioned, they are subjected to a heat treatment together with a reductant, such as carbon, calcium silicide or aluminum, or any other reductant that provides volatile oxides, such as silicon, for example, at a temperature below the melting point of the oxide, in a heat treatment furnace; - the obtained spongy mass is crushed; - then it is subjected to a heat treatment, at a temperature higher than the melting point of the metal, in an electron beam oven.
