  2. Uranate - Wikipedia

    en.wikipedia.org/wiki/Uranate

    A uranate is a ternary oxide involving the element uranium in one of the oxidation states 4, 5 or 6. A typical chemical formula is M x U y O z , where M represents a cation. The uranium atom in uranates(VI) has two short collinear U–O bonds and either four or six more next nearest oxygen atoms. [ 1 ]

  3. Sodium diuranate - Wikipedia

    en.wikipedia.org/wiki/Sodium_diuranate

    Sodium diuranate, also known as the yellow oxide of uranium, is an inorganic chemical compound with the chemical formula Na 2 U 2 O 7. It is a sodium salt of a diuranate anion. It forms a hexahydrate Na 2 U 2 O 7 ·6H 2 O. Sodium diuranate is commonly referred to by the initials SDU. [1] Along with ammonium diuranate it was a component in early ...

  4. Ammonium diuranate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_diuranate

    Ammonium diuranate or (ADU) ((NH 4) 2 U 2 O 7), is one of the intermediate chemical forms of uranium produced during yellowcake production. The name "yellowcake" originally given to this bright yellow salt, now applies to mixtures of uranium oxides which are actually hardly ever yellow.

    Ball-and-stick model of UO 2+ 2 The uranyl ion, showing the U–O bond order of 3. The uranyl ion is an oxycation of uranium in the oxidation state +6, with the chemical formula UO 2+

  6. Uranium trioxide - Wikipedia

    en.wikipedia.org/wiki/Uranium_trioxide

    Like all hexavalent uranium compounds, UO 3 is hazardous by inhalation, ingestion, and through skin contact. It is a poisonous, slightly radioactive substance, which may cause shortness of breath, coughing, acute arterial lesions, and changes in the chromosomes of white blood cells and gonads leading to congenital malformations if inhaled.

  7. Yellowcake - Wikipedia

    en.wikipedia.org/wiki/Yellowcake

    The compositions were variable and depended upon the leachant and subsequent precipitating conditions. The compounds identified in yellowcakes include uranyl hydroxide, uranyl sulfate, sodium para-uranate, and uranyl peroxide, along with various uranium oxides. Modern yellowcake typically contains 70% to 90% triuranium octoxide (U 3 O 8) by weight.

  8. Uranyl peroxide - Wikipedia

    en.wikipedia.org/wiki/Uranyl_peroxide

    Uranyl peroxide or uranium peroxide hydrate (UO 4 ·nH 2 O) is a pale-yellow, soluble peroxide of uranium.It is found to be present at one stage of the enriched uranium fuel cycle and in yellowcake prepared via the in situ leaching and resin ion exchange system.
