Chromite is the most important chromium ore mineral. It forms a complete solid solution series with many other members of the group, eg. in the Chromite-Hercynite Series, Chromite-Spinel Series, Chromite-Magnetite Series and the Chromite-Magnesiochromite Series.It is the iron analogue of Zincochromite, Cochromite, Manganochromite and …









Specifically, Fe 56.8 Cr 18.9 Ni 15.1 Al 4.6 Ti 4.6 exhibits a good combination of a high strength of 1142 MPa and an elongation strain of 9.5%. The excellent tensile properties of this alloy are attributed to the synergetic effects of a soft FCC phase, a hard BCC phase, and the uniform distribution of high-density L2 1 nanoparticles in BCC matrix.











Kimyasal analiz sonuçlarına göre kromit %Cr2O3 42,03-52,1, Cr/Fe oanı 3,794- 4,216 arasında, PGE içeriklerinde; Ru oranı 90 ile 130 ppb, Ir oranı 24 ile 40 ppb, Os oranı 13 ile 50 ppb ve Rh oranı 6 ile 11 ppb arasında değişmektedir.

Fe 2+ + Cr → Fe + Cr 3+ Solution. We start by writing the two half reactions. Chromium is being oxidized, and iron is being reduced: Cr → Cr 3+ oxidation Fe 2+ → Fe reduction. Then we include the appropriate number of electrons on the proper side to balance the charges for each reaction: Cr → Cr 3+ + 3e − Fe 2+ + 2e − → Fe







In this work, we performed density functional theory (DFT) calculations with inclusion of Hubbard U corrections for the transition metal d-electrons, to investigate stability and electrocatalytic activities of the oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) for the ABO 3 (A = La; B = Cr, Mn, Fe, Co, and Ni) (001) surfaces. We …
