What is Triiron Tetraoxide？

Triiron Tetraoxide is a mixed-valence iron oxide appearing as a black magnetic powder. It is insoluble in water and organic solvents, but soluble in concentrated acids. The compound occurs naturally as the mineral magnetite and is the most magnetic of all naturally occurring minerals. It is widely used in electronic materials, pigments, and medical applications due to its unique magnetic and electrical properties.
