   You may wish to watch that video by NurdRage titled  "Make Iron Oxide (for   
   Thermite)"   
      
   Everyone else Considering thermite needs Iron(III)oxide Fe2O3 and that is the   
   main component of hematite.   
      
   Based on the video, I suspect that you are over volting and loosing lots of   
   energy to heat and releasing oxygen gas to bubble out of solution faster than   
   the iron can oxidize it.
