Uranium(III) chloride , UCl3, is a chemical compound that contains the earth metal uranium and chlorine. UCl3 is used mostly to reprocess spent nuclear fuel. Uranium(III) chloride is synthesized various ways from uranium(IV) chloride; however, UCl3 is less stable than UCl4.
Additional recommended knowledge
There are two ways to synthesize uranium(III) chloride. The following processes describe how to produce uranium(III) chloride.
(1) In a mixture of NaCl-KCl at 670-710 °C, add uranium tetrachloride with uranium metal.
(2) Heat uranium(IV) chloride in hydrogen gas.
In the uranium(III) chloride molecule, three chlorine atoms are bonded around a uranium center in a tricapped trigonal prismatic configuration. A tricapped trigonal prismatic configuration has a configuration number of nine.
Uranium(III) chloride is a green crystalline solid at room temperature. UCl3 melts at 837 °C and boils at 1657°C. Uranium(III) chloride has a density of 5500 kg/m³ or 5.500 g/cm³.
Its composition by weight:
Its formal oxidative states:
The molten form of uranium(III) chloride is a typical compound in pyrochemical processes as it is important in the reprocessing of spent nuclear fuels.UCl3 is usually the form that uranium takes as spent fuel in electrorefining processes.,
There are three hydrates of uranium(III) chloride:
While there are no long-term data on the toxic effects thas UCl3, it is important to minimize exposure to this compound when possible.
Similar to other uranium compounds that are soluble, UCl3 is likely absorbed into the blood through the alveolar pockets of the longs within days of exposure. Exposure to uranium(III) chloride leads to toxicity of the renal system.
