FAQ: Professional FAQ on Fe3O4 Powder Iron Oxide

Frequently Asked Questions

1. What is the main difference between Fe3O4 Powder Iron Oxide and Fe2O3 red iron oxide pigment?

Fe3O4 Powder Iron Oxide is a mixed-valence (Fe(II), Fe(III)) oxide known for its strong magnetic properties and jet black appearance, in contrast to Fe2O3, which is a trivalent (Fe(III)) oxide and typically red or brown with non-magnetic characteristics. Fe3O4 is thus preferred for magnetic, catalytic, or advanced functional applications.
