Upon the surface of this multi-aspected crystal are carved the myriad deeds of paladins from eras past.

'Chromite' is commonly used for any Cr-rich mineral of the spinel group, particularly for the chromite-magnesiochromite series, and much of the mineral referred to as 'chromite' in geological and petrological papers and mining statistics is magnesiochromite.

Chromite is a typical refractory igneous mineral, precipitated from mafic magmas at relatively high temperatures. Chromites commonly occur in sedimentary, metamorphic, and metasomatic rocks, where they are interpreted as relics of an igneous phase and serve as the source of Cr for low-temperature Cr-bearing minerals.

To a solution of 4,5,6,7-tetrahydroazepino[3,2,1-hi]indole-1-carboxylic acid (1.4 g, 6.5 mmol) in 7.5 mL of quinoline was added copper chromite (0.55 g, 1.77 mmol). The resulting mixture was stirred at 185° C. for 4 hours and then cooled to room temperature, diluted with dichloromethane and filtered through Celite.

Chromium builds do not auto-update, and do not have symbols. This makes them most useful for checking whether a claimed fix actually works. Use the following instructions to find builds:

We present results of first-principles density functional calculations for the candidate multiferroic magnetoelectric, bismuth chromite. Although little is known experimentally about BiCrO3, its chemical neighbors BiMnO3 and BiFeO3 are known to be ferromagnetic and ferroelectric respectively, with structural distortions driven by the strongly polarizable Bi ions.

Chromite is an iron chromium oxide: FeCr 2 O 4.It is an oxide mineral belonging to the spinel group.Magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr 2 O 4); substitution of aluminium occurs leading to hercynite (FeAl 2 O 4).
