Abstract

En un procedimiento para producir polvo de metal no ferroso sustancialmente libre de oxido de un metal que tiene un potencial de reducción de oxidación entre cadmio y plata inclusive, incluyendo dicho método el paso de reaccionar un sistema acuoso que contiene una sal de por lo menos uno de dichos metales con un gas reductor a temperatura y presión elevadas, la mejora que comprende proporcionar en dicho sistema una cantidad finita de un agente de adición que comprende un polímero de etileno de anhídrido maleico.In a process for producing non-ferrous metal powder substantially oxide-free of a metal having an oxidation reduction potential between cadmium and silver inclusive, said method including the step of reacting an aqueous system containing a salt of at least one of said metals with a reducing gas at elevated temperature and pressure, the improvement comprising providing in said system a finite amount of an addition agent comprising an ethylene maleic anhydride polymer.
