2. Ellingham diagram is used to predict thermodynamic feasibility of reduction of oxides of one metal by another metal. Any metal can reduce the oxides of other metals that are located above it in the diagram. For example, in the Ellingham diagram, for the formation of chromium oxide lies above that of the aluminium, meaning that Al 2 O 3

Chromium is a ferrite stabilizer and a strong carbide former. Addition of chromium improves strength, oxidation resistance, and corrosion resistance properties. Therefore, the global production of chromium has gained importance over the years. Chromium is not obtained in its free state; therefore, chromium ore is reduced by normal smelting process.

Chromium is not added directly to the steel but in the form of ferrochrome, as the latter has a lower melting point. Many minerals contain chromium, but chromite is the only mineral from which chromium is extracted . The global ferrochrome market was valued at USD 16.10 billion in 2022 and is projected to grow to USD 24.03 billion by 2030.
