Yellowcake?!?!?!?

How come that U3O8 is a yellowcake, when yellowcake is made FROM U3O8 (and UO2)??? Yellowcake is mainly (NH4)2U2O7 and not U3O8.......Eudialytos (talk) 16:31, 19 August 2020 (UTC)

Indeed, this is a common point of confusion: Yellowcake is simply a colloquial name for "Uranium Ore Concentrate" or UOC, which can take many chemical forms depending on the source of the ore material and the mining and milling steps used to extract uranium from the mineral. The name Yellowcake comes from the face that one common form of UOC is, as you mentioned, ammonium diuranate, (NH4)2U2O7, but other common forms also exist, such as U3O8 (which is green-black). I hope this clarifies the matter ;-) Patrick A Burr (talk) 21:36, 11 February 2021 (UTC)

missing reference for Bond Valence Study

The last section fo the article, Bond Valence Study, has no reference, and appears to be the conclusion of a single study. Also, it appears to me that the summary does not reflect the true results of the study, as the first sentence is inconsistent with the rest of the section (if the box contained a single U atom, rather than a U3O8 crystal structure, it would not be possible to ascertain the oxidation state of the two uranium species in the crystal by population analysis, Bader charger or other similar method).

Most studies I've been able to find, like this one, suggest that it's made up of 2x U(V) and 1x U(VI) per formula unit. Maybe a complete reworking of the "bond valence study" section would be better, like this.

Proposed major revision

Hey everyone! I've been working on improving this article at User:UnbihexiumFan/Triuranium octoxide. What do you people think? Is it good enough to be moved over here? UnbihexiumFan (talk) 22:33, 11 March 2025 (UTC)

Probably a bit late to say this, but I have moved it over here.
