Abstract
A process for manufacturing of metal powder from a halogen containing chemical compound of the metal. The process involves thermal treatment of the compound within a closed reactor and in non-oxidizing atmosphere so as to induce decomposition of the compound and formation therefrom of a metal halide and a reduction agent capable to reduce the metal halide to elemental metal which can be collected in the form of fine powder. By variation of condition of the thermal treatment like temperature, pressure, duration and by choosing particular type of the compound it is possible to control the size and purity of the powder as well the powder particles shape.
