Conclusions
-
1.
The formation of cervantite in the temperature range examined is limited by nucleation; the crystallographic similarity of cervantite and valentinite means that the oxidation of the latter begins with the formation of an epitaxial film of cervantite on the valentinite.
-
2.
This epitaxial layer acts as an efficient nucleus on which material is deposited: from the valentinite by bulk diffusion and from the senarmontite via the gas phase and by surface diffusion.
