Asf Institute answered |
- Spinels have a general formula AB2O4 and are classified as either normal or inverse.
- In a normal spinel, A2+ ions occupy the tetrahedral sites, and B3+ ions are in octahedral sites.
- In an inverse spinel, half of the B3+ ions and all A2+ ions occupy octahedral sites, while the remaining ... more
- CoFe2O4 is inverse because Co2+ prefers octahedral sites.
- FeFe2O4 (magnetite) is also inverse with Fe3+ ions distributed as described.
