Question:
Can electrolytic iron powder be used for MIM. Are there any technologies that can be used to make it spherical?

Answer:
I am not aware of any one making MIM parts with electrolytic iron powders, but that does not mean it is not possible to do so.   Most feedstock materials are made from near spherical powders, such as carbonyl iron powders or gas atomized powders, which permit smooth flow of the feedstock into the mold with a reduced binder content.  But there are also manufacturers who make parts consistently with water atomized powders which are irregular in shape.

Electrolytic powders are dendritic in shape, which poses a special challenge in making consistent feedstock.  However if Mr. Dhoka as a major stake holder in a company manufacturing electrolytic iron powder has the will to make feedstock with dendritic powders and it makes economic sense to do so, overcoming the challenge is only a function of knowledge, talent, time and money.

I am not so sure how you could make the dendritic powders spherical without causing the particles to agglomerate or pan cake.
