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 …

The meaning of URANATE is a compound [as calcium uranate CaUO4 or ammonium di-uranate (NH4)2U2O7] formed by reaction of a uranyl salt with a base or by fusion of uranium trioxide or tri-uranium oct-oxide with a metal chloride.

Sodium diuranate, also known as the yellow oxide of uranium, is an inorganic chemical compound with the chemical formula Na2U2O7. It is a sodium salt of a diuranate anion. It forms a hexahydrate Na2U2O7·6H2O. Sodium diuranate is commonly referred to by the initials SDU. [1] .

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 MxUyOz, where M represents a cation. The uranium atom in uranates has two short, co-linear, U-O bonds and either four …

Uranate definition: (inorganic chemistry) Any of several oxyanions of uranium ; any salt containing these anions.

1999年9月1日 · Today there are many routes to uranate(VI), viz., reacting uranium oxides with alkali metal oxides, peroxides, superoxides, nitrates, nitrites, sulfates, chlorides, chlorates and bromates in the presence of air or oxygen in the solid state or in a suitable molten salt.

2021年11月1日 · This work provides insight into UO 2 alteration and the persistence and stability of ammonium uranate which have implications for ideal fuel pellet sinterability, nuclear forensics, environmental management, and fundamental solid-state uranium chemistry.

2017年3月31日 · It has been found practically impossible to obtain a precipitate that does not carry considerable quantities of vanadium, most of which appears probably as uranium vanadate. The filtrate from the sodium uranate precipitate contains the vanadium as sodium vanadate.

Uranate is the chemical term for oxide anions of the element uranium. Examples of uranates include UO 2 −2, UO 3 −2, and UO 4 −2.

If a solution of a uranyl salt is mixed with one of ammonia, or potash, or soda, the uranium is precipitated in the form of a uranate, U 2 O 6 R 2 O, of the respective alkali. Encyclopædia Britannica, Ninth Edition/Uranium – Wikisource. Dictionary …
