The Chemical Reactions That Make Hand Warmers Heat Up

IRON POWDER. Oxygen in the air reacts with this powder to yield iron oxide—rust—and heat. These hotties can reach up to 163 degrees Fahrenheit; militarygrade warmers (for heating MREs) can get to upwards of 200 degrees. Manufacturers produce iron powder by either crushing iron or spraying a molten stream with water.

Cast Thermite: 6 Steps

That is a 'better' way to get iron oxide, if you're looking for efficiency from cost/time/endproduct mass Vs. beginning mass. There is one thing that you did not consider, though, and that is the fact that when you make iron oxide via electrolysis you do not have an end product of Fe2O3 which is the best iron oxide to use for thermite mixtures.
