    www.sciencedirect.com/science/article/pii/S0277538708007201 The conditions favouring the formation of chukanovite Fe 2 (OH) 2 CO 3 at the detriment of Fe(II) hydroxide Fe(OH) 2, often considered as the first solid forming from the Fe(II) dissolved species generated by the dissolution of steel, were determined. Chukanovite was the unique compound to form for R > 1 and R′ > 0.5.

    www.sciencedirect.com/science/article/pii/S0010938X14001553 Chukanovite (Fe 2 (OH) 2 CO 3) has been identified by synchrotron-sourced infrared microspectroscopy as the main corrosion product at the sand-deposited carbon steel corroded in CO 2-saturated brine at 80 °C.Siderite has been shown as a minor corrosion product at the sand-deposited steel, and the only product at the sand-free steel. The sand-deposited steels have similar general corrosion ...

    geoscience.wisc.edu/astrobiology/wp-content/.../Lee_Xu_2018_Chem_Geol.pdf Rietveld refinement of the chukanovite structure shows it is as expected monoclinic, space group of P2 1/a, with a=12.402(2), b=9.414(1), c=3.216(1) Å, β=97.73(3)°. The standard Gibbs free energy of formation of chukanovite is estimated at −1167.2 ± 1.2kJmol−1 from the equilibrium between siderite and chukanovite.

    www.osti.gov/pages/biblio/1411232 Abstract. Here, a solubility model is presented for ferrous iron hydroxide (Fe(OH) 2 (s)), hibbingite (Fe 2 Cl(OH) 3 (s)), siderite (FeCO 3 (s)), and chukanovite (Fe 2 CO 3 (OH) 2 (s)). The Pitzer activity coefficient equation was utilized in developing the model to account for the excess free energies of aqueous species in the background solutions of high ionic strength.
