ABSTRACT:
The process for the synthesis of rhenium powders comprises the injection of ammonium perrhenate powder through a carrier gas in a plasma torch of a plasma reactor operated using a mixture including hydrogen as the plasma gas, yielding metallic rhenium under the following chemical reaction:in-line-formulae description="In-line Formulae" end="lead"?2NH4ReO4+4H2→2Re+N2↑+8H2O↑.in-line-formulae description="In-line Formulae" end="tail"?The reactor is provided with a quench zone for cooling the metallic rhenium so as to yield rhenium nano and micro powders.
