Chromite is a crystalline mineral composed primarily of iron (II) oxide and chromium (III) oxide compounds. It can be represented by the chemical formula of Fe Cr 2 O 4. It is an oxide mineral belonging to the spinel group.

2023年4月23日 · Chromite is an oxide mineral that an iron chromium oxide with formula: FeCr2O4. It is belonging to the spinel group. Chromite is the most important ore of chromium. Crystals are uncommon, but when found they are octahedral. Chromite is usually massive or in the form of lenses and tabular bodies, or it may be disseminated as granules.

Chromite, relatively hard, metallic, black oxide mineral of chromium and iron (FeCr2O4) that is the chief commercial source of chromium. It is the principal member of the spinel series of chromium oxides; the other naturally occurring member is magnesiochromite, oxide …

Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4). It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity.

"Chromites" associated with olivine or serpentines, which are Mg-rich rocks, frequently have Mg-rich associated minerals. True chromite is common as inclusions in diamonds from kimberlites (South Africa and Yakutia).

Chromite is a mineral with formula of Fe 2+ Cr 3+2 O 4 or Fe 2+ Cr 2 O 4. The IMA symbol is Chr. Conformer generation is disallowed since MMFF94s unsupported element, mixture or salt. dioxido (dioxo)chromium;iron (2+) Computed by LexiChem 2.6.6 (PubChem release 2019.06.18) InChI=1S/Cr.Fe.4O/q;+2;;;2*-1.

Chromite is an oxide mineral belonging to the spinel group, a complex mineral containing magnesium, iron, aluminum, and Cr in varying proportions, depending on the deposit, that can be represented as FeCr 2 O 4 or (Fe 2+,Mg) [Cr,Al,Fe 3+] 2 O 4 (Murthy et al., 2011; Sanchez-Segado et al., 2015).

Chromite is a member of the spinel group of minerals and consists essentially of ferrous and chromic oxides—FeO, Cr2 O 3, analogous to aluminates. Ferrous oxide is, however, often partly replaced by magnesia and chromic oxide by alumina so that there is a transition to chrome spinel or picotite (MgFe)O. (AlCr) 2 O 3.

2024年10月4日 · Chromium ore is a naturally occurring mineral. Odisha is the sole producer of chromite in India. Know all about Chromium Ore, Properties, Uses, & Distribution Map in this article for UPSC exam. Chromium is an important metal used to make strong alloys with other metals like nickel, cobalt, and copper.

Chromite is the main source of the metal chromium, a metal used to induce hardness, toughness and chemical resistance in steel. It was named after its chemical composition, chromium oxide. The mineral is brownish to black in colour with a dark brown streak. It has a conchoidal or an uneven fracture as well as no distinct cleavage.
