DESCRIPTION

Iron oxide black

The combination models of iron oxide black products are 5330 and 720. Their hiding power and coloring power are very high, and their effect on light and atmosphere is very stable, like all cosmic stars ® Iron oxide series products provide good color consistency and stability. The main component of iron oxide black is iron tetroxide, which is a black crystal with magnetic properties. It can be approximately regarded as a compound of iron oxide and ferrous oxide. Iron oxide black is soluble in acid solutions and insoluble in water, alkali solutions, ethanol, ether and other organic solvents. It is applicable to paint making in coating industry and cement coloring in construction industry.

Typical Properties

Iron oxide black is a black powder. It is an adduct of iron oxide and ferrous oxide. Generally, the content of ferrous oxide is very high and the covering power is very high. Coloring power is great, but not as good as carbon black. It has a stable effect on the sun and the atmosphere. Resistant to all alkalis, but soluble in acid and has strong magnetism. Calcined in the presence of sufficient air, it is easy to be oxidized to iron oxide red. It is mainly used for making primer and finish paint, and also used as antirust agent in construction industry. High purity is an excellent magnetic material, which is used to coat audio tapes. As an important iron pigment, iron oxide black is widely used in watercolor and ink. The main raw material of magnetic toner for copier is needle iron oxide black. In addition, iron oxide black can also be used in the production of high-grade cosmetics because of its non-toxic and pollution-free characteristics.
