WebFormula chimica: Fe 3 O 4: Proprietà cristallografiche; Gruppo cristallino: monometrico Sistema cristallino: cubico, isometrico: Classe di simmetria: Esottaedrico: Gruppo puntuale: ... La magnetite è facilmente riconoscibile all'interno di vecchi radiatori di riscaldamento (termosifoni) in ferro e ghisa ed è la responsabile del colore nero ... WebThe ionic model of magnetite is considered as Fe 3+ [Fe 3+ Fe 2+] O 42–. The crystals are cubic with an inverse spinel structure. The cations [Fe 3+, Fe 2+] are in the octahedral sites. The Fe 3+ is half in tetrahedral and half in the octahedral sites. The spontaneous magnetism exhibited by magnetite is therefore entirely due to Fe 2+ per Fe 3 O 4.
