What is FeCr2O4? Important knowledge about FeCr2O4.

  1. Definition of FeCr2O4
    FeCr2O4, often referred to as Iron Spinel, or Iron Chromite in English as Iron(II) Chromite. It is a chemical compound consisting of Fe, Cr, and O. The molar mass of this compound is 223.84 g/mol. Its molecular structure consists of 1 iron atom (Fe), 2 chromium atoms (Cr), and 4 oxygen atoms (O). FeCr2O4 has an ionic structure based on the spinel lattice, in which the central cation is usually Fe2+, while chromium and oxygen form an octahedral network around it.

  2. Properties of FeCr2O4
    FeCr2O4 is typically in solid state, with color ranging from black to reddish brown. The chemical properties of FeCr2O4 include high temperature resistance and reaction with acid to form salts of iron and chromium.

  3. Common Chemical Equations of FeCr2O4
    FeCr2O4 mainly participates in redox reactions. Some typical reactions include the reaction with hydrochloric acid to produce Iron(III) Chloride hexahydrate and Chromium(III) Chloride hexahydrate, or reaction with sulfuric acid to produce Iron(III) Sulfate and Chromium(III) Sulfate.

  4. Synthesis of FeCr2O4
    FeCr2O4 is usually synthesized in the laboratory through the reaction between Iron(II) Oxide and Chromium(III) Oxide in a high-temperature environment. Industrially, FeCr2O4 is produced as a by-product in the process of smelting chromium from chromite ore.
