It is antiferromagnetic with a Néel temperature of 475 K. However, ferrochrome as a starting material requires a prior separation of the iron.Įxtremely pure chromium is produced by further purification steps using the van-Arkel-de-Boer process.įerrochrome is produced by reducing chromite in an electric arc furnace at 2800 ° C.Ĭhromium is a silver-white, corrosion- and tarnish-resistant hard metal that is tough, malleable and malleable in its original state. Corresponding solutions are prepared by dissolving chromium (III) oxide or ferrochrome in sulfuric acid. Purer chromium is made by electrodepositioning the Cr 3+Ions from sulfuric acid solution shown. This is followed by the aluminothermic reduction of the chromium (III) oxide to chromium:Ĭhromium cannot be obtained from oxidic ores by reduction with coal, since this creates chromium carbide. A subsequent reduction with carbon gives chromium (III) oxide: The sodium dichromate crystallizes on cooling as a dihydrate from the solution. The sodium chromate is extracted with hot water and converted into dichromate with sulfuric acid: In the second step, an oxidizing digestion takes place at approx. The extracted chromite ore is freed from the dead rock. The compounds of chromium have many different colors and are often used as pigments in paints and varnishes. It belongs to the transition metals, in the periodic table it is in the 6. Χρῶμα chrṓma, color ') is a chemical element with the element symbol Cr and the atomic number 24. The electronic configuration of Chromium will be 1s2 2s2 2p6 3s2 3p6 3d5 4s1.Chromium (alt. How do you write the electron configuration for Chromium?
