General description

Iron(II) chloride, also known as Ferrous chloride, is a solid with paramagnetic properties and a high melting point. In general, the synthesis of ferrous chloride involves the addition of iron powder to a solution of hydrochloric acid in methanol. This reaction results in the formation of the methanol solvate of dichloride. Subsequently, by subjecting the solvate to vacuum and heating it at around 160 °C, the solvate transforms into anhydrous ferrous chloride (FeCl2).[1]Iron(II) chloride exhibits solubility in tetrahydrofuran (THF), making it a crucial precursor material for the synthesis of organometallic compounds.[2]
We are committed to bringing you Greener Alternative Products, which belongs to one of the four categories of greener alternatives. This product belongs to an Enabling category, and is used in the electrodeposition of iron-aluminum alloys for thermoelectric applications, enhancing energy conversion efficiency. This process, utilizing molten salt systems, contributes to sustainable energy technologies and supports the development of advanced materials for eco-friendly energy storage and conversion. Click here for more information.

Application

Thermoelectric materials have gained attention for their ability to directly convert temperature differences into electrical energy. High purity Iron(II) chloride, is used as a precursor for the synthesize of Heusler-type iron-based thermoelectric materials, Fe2XAl (X = V, Ti, etc.) for the use in thermoelectric conversion. For example: the binary Fe-Al thin films are synthesized using electrodeposition method in Iron(II) chloride containig quaternary molten salts which exhibited p- or n-type thermoelectric conversion, depending on their composition.[3] In addition, our high purity Iron(II) chloride, anhydrous is also used as a source of Iron to produce supercapacitor material such as heteroatom -dopped porus carbon. In the synthesis process, Iron(II) chloride is used as catalyst and template to shape the structure of the electrode with large specific surface area, high specific capacitance along with excellent rate capability and cycle stability due to the combination of in situ molten salt templating and chemical blowing.[4]
