WebThe Cuban chromites with a spinel structure, FeCr2O4 have been studied using optical absorption and EPR spectroscopy. The spectral features in the electronic spectra are used to map the octahedral and tetrahedral co-ordinated cations. Bands due Cr3+ and Fe3+ ions could be distinguished from UV-vis s … WebAs shown above, chromites in equilibrated chondrites have constant compositions with a narrow range of Fe/(Fe + Mg) and Cr/(Cr + Al) ratios. The chromites deviating from the average compositions listed in Table 1 have also constant compositions. But some chondrites in addition contain grains with variable Cr/(Cr + Al) and Fe/(Fe + Mg) ratios ...

WebJan 18, 2024 · The chromites in the Black Thor Intrusive Complex exhibit a wide range of textures including (1) massive, (2) inclusion-bearing (predominantly serpentine-actinolite-chlorite interpreted to represent altered komatiitic melt inclusions), and (3) pitted with fine Fe ± Cu sulfides ( Fig. 3A ). WebNov 30, 2024 · In terms of the total power consumption for smelting HCFC, the process with prereduction is more efficient than the processes involving heating and sintering of the charge at a degree of metallization of chromium higher than 50% for South-Africa chromites and 65% for Kazakhstan chromites. 2. WebCopper chromite is a black powder and inorganic pigment thatadopts a spinel crystal structure. It can be made by the high-temperaturecalcination of copper(II) oxide and chromium(III) oxide or the thermaldecomposition of copper chromate, which evolves oxygen at higher temperaturesand decomposes to copper chromite. chupke chupke raat din song
