    Iron ore consists primarily of hematite (Fe 2 O 3) and magnetite (Fe 3 O 4) in proportions which vary appreciably among ore bodies, as well as variously hydrated hematites, siderite (FeCO 3), and pyrite (FeS 2). Among impurities present, again in widely varying proportions, the most important are lime (CaO), silica (SiO 2) and alumina (Al 2 O 3).

    Iron oxide or hematite (α-Fe 2 O 3) has also been under investigation since the late 1970s [80] due to its high stability and small band gap of 2.0–2.2 eV [81]. The major drawbacks to hematite are an improper conduction band potential [81] and a very short hole diffusion distance (2–4 nm) [82].

    Hematite's popularity in jewelry rose in England during the Victorian era, due to its use in mourning jewelry. Certain types of hematite- or iron-oxide-rich clay, especially Armenian bole, have been used in gilding. Hematite is also used in art such as in the creation of intaglio engraved gems.
