Iron (III) oxide Iron(III) oxide or ferric oxide is the inorganic compound with the formula Fe2O3. It is one of the three main oxides of iron, the other two being iron(II) oxide (FeO), which is rare, and iron(II,III) oxide (Fe3O4), which also occurs naturally as the mineral magnetite. As the mineral known as hematite, Fe2O3 is the main source of iron for the steel industry. Fe2O3 is ferromagnetic, dark red, and readily attacked by acids. Iron(III) oxide is often called rust, and to some extent this label is useful, because rust shares several properties and has a similar composition.

Aluminium chloride Aluminium chloride is hygroscopic, having a very pronounced affinity for water. It fumes in moist air and hisses when mixed with liquid water as the Cl − ions are displaced with H 2 O molecules in the lattice to form the hexa hydrate AlCl 3 ·6H 2 O (also white to yellowish in color).n the melt, aluminium trichloride exists as the dimer Al 2 Cl 6, with tetracoordinate aluminium. This change in structure is related to the lower density of the liquid phase (1.78 g/cm 3) vs solid aluminium trichloride (2.48 g/cm 3).

Aluminium (I) oxide From Wikipedia, the free encyclopedia. Aluminium(I) oxide is a compound of aluminium and oxygen with the chemical formula Al 2 O. It can be prepared by heating the stable oxide Al2O3 with elemental silicon at 1800 °C under vacuum.l 2 O commonly exists as a gas, since the solid state is not stable at room temperature and is only stable between 1050 and 1600 °C. Aluminium (I) Oxide is formed by heating Al and Al 2 O 3 in vacuo while in the presence of SiO 2 and C, and only by condensing the products.
