If you want to synthesize magnetite you can use co-precipitation method: mix Fe3+ and Fe2+ precursors with molar ratio of 2:1 in the DI water. Then add ammonia solution (or KOH, NaOH, or any other basic salt) until the pH increase to 10. Then the black magnetite is ready.
Magnetite is an iron-oxideiron-oxideIron oxide pigment. The brown color indicates that iron is at the oxidation state +3. Green and reddish brown stains on a limestone core sample, respectively corresponding to oxides/hydroxides of Fe2+ and Fe3+.https://en.wikipedia.org › wiki › Iron_oxideIron oxide – Wikipedia mineral that occurs naturally on Earth. Because it is also an important component of many anthropogenic materials (e.g., coal fly ash) and synthetic products (e.g., black toner powders), magnetite can be released to the environment through human activities (1).
Magnetite is a mineral whose primary component is an iron oxide that contains equal amounts of iron(II) and iron(III). Its empirical formula is Fe3O4, and it is often expressed as iron(II,III) oxide.
Magnetite is a common natural phase, occurring in various geological environments, ranging from igneous (e.g., layered ultrabasic rocks, basalts) to sedimentary (e.g., banded iron formations, beach sands) rocks, and to high-grade metamorphic rocks (e.g., schists, skarns), where it can be produced through a multitude of …
