Personal collection of memorable FeCO3 literature

I have kept notes at so many places that I keep forgetting a lot of literature. I am keeping this as notes of things as I remember them over time. As one can see, there are some papers that are quite old, and the knowledge has progressed since the time they were published. However, the results hardly get old, it is only the analysis that improves over time. This is not at all an exhaustive list of literature: in fact, it is far from it. These are the things that I fear I will forget over time or have already forgotten when I am looking at them.

1. The degree of supersaturation must be much larger than unity for the formation of dense and protective layer: Corrosion Science, 2007

2. To calculate the degree of supersaturation. Corrosion Science, 1999

3. Different papers have proposed different sources of direct acid reduction:

   1. Direct H2CO3 reduction as dominant when 4<pH<5. Corrosion, 1975

   2. Direct reduction of HCO3- when pH>5. Corrosion, 1987

   3. Direct H+ reduction when pH<4. Corrosion, 1996

4. Direct H+ reduction theory seems to be winning. Not it is said that all the earlier confusion in the interpretation of older results was because of the buffering effect (possible conversion of H2CO3 into H+ in the solution, while the new H+ attacks the surface). NACE, 2015: This also shows how the indirect method of analysis can influence the observation, especially when the cause and effect are not easy to delineate.

5. FeCO3 can be synthesized if you mix in an anaerobic environment: (a) 0.5M Ferrous ammonium sulfate, with (b) 0.75 M sodium bicarbonate. Follow this by Ostwald ripening for 48 h at 75C: FeCO3 was found to be quite stable in ripened form, and unstable conversion to Fe2O3 if not ripened. Corrosion Science, 1999

6. FeCO3 nucleation is usually considered to be so fast that it is not considered in the modeling. The precipitation rate is considered to be dependent on crystal growth than nucleation. If nucleation is too slow too, the scale can be porous.

7. CO2-sequestration using Iron oxyhydroxides by reducing with sulfide and then reacting with scCO2. Env. Sc. Tec. 2011

8. FeCO3 can be synthesized by the hydrothermal decomposition of Fe(III)-EDTA complex in the presence of urea, starting from ferric ammonium sulfate and Na4EDTA as the main precursors. The paper also has FTIR. Cry. Gro. Des. 2011
