Magnetite

Recommended Posts

Hi,

 

I'm having trouble making magnetite from FeCl2/FeCl3 and Sodium Hydroxide.

 

I have a bottle of PCB etchant (FeCl3), put some in a beaker, added steel wool to reduce it to FeCl2. Then filtered, added FeCl3 and began adding NaOH.

 

The problem is this:

 

Iron Hydroxide is forming? I don't know how to stop that, I'm getting little Fe3O4 and lots of Iron Hydroxide. I thought it was the Etchant (impure) so I dissolved iron filings in HCl to get FeCl2. I added FeCl3.. and did the same procedure.. with the same result =(

 

I'm not sure what to do? Any ideas on better ways of synthesizing Fe3O4 or where in can buy it (other than online of course , because i need it rather quickly)

 

Thanks
