Triiron Tetraoxide CAS #1317-61-9

Products Description of Direct Triiron Tetraoxide CAS #1317-61-9

Triiron tetroxide (Fe₃O₄) is naturally derived from magnetite, a naturally occurring iron oxide mineral. In laboratory preparation, it can be synthesized by adding sodium hydroxide solution to an aqueous solution containing a 1:2 molar ratio mixture of ferrous and ferric salts (such as 1 mol FeCl₂ and 2 mol FeCl₃). The resulting black hydroxide precipitate undergoes dehydration upon heating to form triiron tetroxide:

Fe²⁺(aq) + 2Fe³⁺(aq) + 8OH⁻(aq) → Fe₃(OH)₈(s)

Fe₃(OH)₈(s) → Fe₃O₄(s) + 4H₂O(g)

Additionally, triiron tetroxide can be produced through the partial oxidation of iron or iron(II) sulfate under controlled heating conditions with limited air supply. Another production method involves the reaction of iron metal with steam at high temperatures:

3Fe + 4H₂O → Fe₃O₄ + 4H₂

These versatile preparation methods enable the production of triiron tetroxide with consistent quality and reliable performance for various applications.
