Then treated with ammonia to produce ammonium diuranate ("ADU", (NH4)2U2O7). Reduction with hydrogen gives UO2, which is converted with hydrofluoric acid (HF) to uranium tetrafluoride, UF4. Oxidation with fluorine yields UF6.

    During nuclear reprocessing, uranium is reacted with chlorine trifluoride to give UF6:

    U + 2 ClF3 → UF6 + Cl2]]>     2018-05-04 19:00:23 UTC https://padlet.com/delainee_gibson548/q78mxg9p3mcl/wish/258142055     How its produced by people delainee_gibson548 https://padlet.com/delainee_gibson548/q78mxg9p3mcl/wish/258261462 Uranyl nitrate can be prepared by reaction of uranium salts with nitric acid. ]]> 2018-05-06 02:54:17 UTC https://padlet.com/delainee_gibson548/q78mxg9p3mcl/wish/258261462 delainee_gibson548 https://padlet.com/delainee_gibson548/q78mxg9p3mcl/wish/259494673 2018-05-10 01:34:11 UTC https://padlet.com/delainee_gibson548/q78mxg9p3mcl/wish/259494673
