MAGNETITE Iron Oxide

Magnetite is an oxide of iron as is hematite It is not a component of ordinary rust although it can form as iron oxidizes in a dry environment When you see sparks from welding operations or from iron striking a hard surface as when it is held against a spinning grinder the sparks are due to the rapid and exothermic oxidation of tiny particles of iron into magnetite...
