Iron Oxide Black | iron oxide black pigment iron oxide | iron oxide black powder

Product performance:

Physical Properties:

Crystalline solid black, insoluble in water, magnetic, solid has good electrical conductivity.

Wire in the pure oxygen combustion generated ferroferric oxide; (phenomenon: sparks, exothermic, black solid - ferroferric oxide generated. When doing the experiment in the lab attention to experiment to put a layer of fine sand or water in the bottle, the reason is: prevent splash down melt burst bottle!) ; The blue gray clastic mainly scattered around the blacksmith's anvil ferroferric oxide; The steam displacement reaction of iron with high temperature generated ferroferric oxide and hydrogen; The main composition of natural magnetite is ferroferric oxide crystals. Ferroferric oxide is a kind of important common iron compounds. Are stable in the air.

In Fe3O4, iron show two valence, a price of ferrous ions + 2, two iron + 3 valence, so ferroferric oxide were classified as composed with Fe2O3 FeO compounds, can be expressed as FeO · Fe2O3, but can't say with mixture of Fe2O3 FeO, it belongs to pure.

Basic performance:

Say again ferroferric oxide, iron oxide black. Molecular weight 231.54, inverse spinel, cubic crystal system, black solid powder, the density of 5.18 g/cm3. The melting point of 1867.5 K (1867.5 ℃).
