  • Efficient Production of Iron(II) Oxide (Fe2O3) 4 Steps

    Introduction Efficient Production of Iron(II) Oxide (Fe2O3) I always thought that blue/black iron oxide had a higher ratio of oxygen than red/brown iron oxide (simple rust) and would be better for using to make thermite. I guess I was wrong. I'm no chemist, but I sure love playing with stuff. 0. frofro . 6 years ago on Introduction. Reply Upvote. would using burnt steel wool as opposed to

  • Iron oxide

    Electrochemically oxidized iron (rust) Iron oxides are chemical compounds composed of iron and oxygen. There are sixteen known iron oxides and oxyhydroxides, the best known of which is rust, a form of iron (III) oxide. Iron oxides and oxyhydroxides are widespread in nature and play an important role in many geological and biological processes.

  • Iron Geoscience Australia

    When iron is exposed to air it starts to turn back into iron oxide and the red powder that forms on the surface of iron is what we call rust. You may have seen rust on old cars or old iron sheds. To make iron stronger and less likely to rust it can be combined with carbon and other elements to make steel. Steel is one of the world's most recycled products, with about 60% of steel available for
