Uranyl peroxide

<a href="/facts/Uranyl/XoqDjPHM">Uranyl</a> peroxide or uranium peroxide hydrate (UO4·nH2O) is a pale-yellow, soluble <a href="/facts/Peroxide/VMU8y4xB">peroxide</a> of <a href="/facts/Uranium/n2sGWBzU">uranium</a>. It is found to be present at one stage of the <a href="/facts/Enriched_uranium/vSb2Tcsb">enriched uranium</a> fuel cycle and in <a href="/facts/Yellowcake/G8S8UQlq">yellowcake</a> prepared via the in situ leaching and resin <a href="/facts/Ion_exchange/C2DPoGqg">ion exchange</a> system. This compound, also expressed as UO3·(H2O2)·(H2O), is very similar to <a href="/facts/Uranium_trioxide/RRK8J8A3">uranium trioxide</a> hydrate UO3·nH2O. The dissolution behaviour of both compounds are very sensitive to the hydration state (n can vary between 0 and 4). One main characteristic of uranium peroxide is that it consists of small needles with an average AMAD of about 1.1 μm.
The uranyl minerals <a href="/facts/Studtite/4aEzhzT1">studtite</a>, UO4·4H2O, and metastudtite, UO4·2H2O, are the only minerals discovered to date found to contain peroxide. The product is a light yellow powder.
