Chemistry name: | uranous-uranic oxide; uranyl uranate
|
M Formula: | U3O8
|
|
Properties: |
Olive-green to black solid, crystals, or granules. D 8.39, decomposes when heated to 1300C to uranium dioxide. Insoluble in water; soluble in nitric acid and sulfuric acid. |
|
Source: |
The naturally occurring uranium oxide found in pitchblende. |
|
Derivation: |
(1) As one of the forms of uranium produced from the ores, often by a solvent extraction process. The solvent used is dodecylphosphoric acid. (2) A common form of triuranium octoxide is yellow cake, the powder obtained by evaporating an ammonia solution of the oxide. |
|
Hazard: |
Radioactive poison. Use appropriate protection in handling. |
|
Use: |
Nuclear technology, preparation of other uranium compounds. |
