Ferrofluid synhesis

  1. May 11, 2007 #1
    I would like to find a way to make a ferrofluid, and I think I have found a viable way using PCB etchant, steel wool, and ammonia to make Magnesite.

    At that point, I am wondering if there is anything more effective to do, starting from household items.

    Also, coating is needed. Wikipedia lists oleic acid (not possible to obtain in pure form -- Omega-9 fatty acid.), tetramethylamonium hydroxide (not really obtainable easily), citric acid (where CAN that be found anyway, in pure form?), and soy lechitin, also hard to find.

    Any pointers to where any of there might be found?

    It's probably way too rudimentary for your purposes, but there's a simple recipe on 'How Stuff Works'. If it isn't adequate, try contacting the author of the article through the site communications system.
