Product Introduction:

Iron oxide black is a black powder with a chemical formula of Fe3O4. It is a magnetic black crystal. It is an adduct of iron oxide and ferrous oxide, so it is also called magnetic iron oxide.

Generally, the content of ferrous oxide has very high hiding power and great coloring power, but it is not as good as carbon black.

C.I. Pigment Black 11 is stable to sunlight and the atmosphere, resistant to all alkalis, but soluble in acid, has strong magnetism, and is easily oxidized into iron oxide red when calcined in the presence of sufficient air.

In recent years, Iron Oxide Black has been loved and sought after by everyone for its excellent performance, low price, and high cost performance.
