  2. Aluminothermic reaction - Wikipedia

    en.wikipedia.org/wiki/Aluminothermic_reaction

    The most prominent example is the thermite reaction between iron oxides and aluminium to produce iron itself: Fe 2 O 3 + 2 Al → 2 Fe + Al 2 O 3. This specific reaction is however not relevant to the most important application of aluminothermic reactions, the production of ferroalloys. For the production of iron, a cheaper reducing agent, coke ...

  3. Cementite - Wikipedia

    en.wikipedia.org/wiki/Cementite

    Cementite forms directly from the melt in the case of white cast iron. In carbon steel, cementite precipitates from austenite as austenite transforms to ferrite on slow cooling, or from martensite during tempering. An intimate mixture with ferrite, the other product of austenite, forms a lamellar structure called pearlite. The iron-carbon phase ...

  4. Transition metal arene complex - Wikipedia

    en.wikipedia.org/wiki/Transition_metal_arene_complex

    The method has been extended to other metals, e.g. [Ru(C 6 Me 6) 2] 2+. In this reaction, the AlCl 3 serves to remove chloride from the metal precursor, and the Al metal functions as the reductant. [1] The Fischer-Hafner synthesis is limited to arenes lacking sensitive functional groups. Structure of Mo(η 6-C 6 H 3 Me 3)(CO) 3.

  5. Haber process - Wikipedia

    en.wikipedia.org/wiki/Haber_process

    Fritz Haber, 1918. The Haber process, [1] also called the Haber–Bosch process, is the main industrial procedure for the production of ammonia. [2] [3] It converts atmospheric nitrogen (N 2) to ammonia (NH 3) by a reaction with hydrogen (H 2) using finely divided iron metal as a catalyst:

  6. Iron compounds - Wikipedia

    en.wikipedia.org/wiki/Iron_compounds

    Iron shows the characteristic chemical properties of the transition metals, namely the ability to form variable oxidation states differing by steps of one and a very large coordination and organometallic chemistry: indeed, it was the discovery of an iron compound, ferrocene, that revolutionalized the latter field in the 1950s. [1]

  7. Metal vapor synthesis - Wikipedia

    en.wikipedia.org/wiki/Metal_vapor_synthesis

    In chemistry, metal vapor synthesis (MVS) is a method for preparing metal complexes by combining freshly produced metal atoms or small particles with ligands.In contrast to the high reactivity of such freshly produced metal atoms, bulk metals typically are unreactive toward neutral ligands.

  8. Cementation (metallurgy) - Wikipedia

    en.wikipedia.org/wiki/Cementation_(metallurgy)

    The reaction is spontaneous because copper is higher on the galvanic series than iron. Cu 2+ (aq) + Fe(s) → Cu(s) + Fe 2+ (aq) This was a historically useful process for the production of copper, where the precipitated solid copper metal was recovered as flakes or powder on the surface of scrap iron. [1]

  9. Cryogenic hardening - Wikipedia

    en.wikipedia.org/wiki/Cryogenic_hardening

    Cryogenic hardening is a cryogenic treatment process where the material is cooled to approximately −185 °C (−301 °F), typically using liquid nitrogen.It can have a profound effect on the mechanical properties of certain steels, provided their composition and prior heat treatment are such that they retain some austenite at room temperature.
