Hydrometallurgical process for producing finely divided iron based powders. |
摘要 |
<p>A process for producing finely divided spherical iron group based metallic powders comprises forming an aqueous solution containing a source of the appropriate metal sources in a mineral acid, forming a reducible iron group based material from the solution, reducing the material to iron group based metal powder particles, subjecting the metal particles to a high temperature zone to melt a portion of the particles and to form droplets and cooling the droplets to form an essential spherical iron group based metallic powders.</p> |
