Hydrometallurgical process for producing irregular shaped powders with readily oxidizable alloying elements

摘要

Composite powders containing a first group of metals of iron, cobalt, nickel and molybdenum in specific ratios and one or more oxidizable metals can be formed by forming an aqueous solution containing first group of metals, forming solid material of the metals from the solution, reducing the solid material to a metallic powder, combining that powder with one or more easily oxidizable metals in an non-oxidizing atmosphere.
