Magnetite / Black Iron Oxide (Fe304) Powder

Magnetite is the most magnetic of all the minerals on Earth. Magnetite is a member of the spinel group which has the standard formula A(B)2O4. The A and B represent different metal ions that occupy specific sites in the crystal structure. In the case of magnetite, Fe3O4, the A metal is Fe +2 and the B metal is Fe +3; two different metal ions in
