Physical and Chemical Properties | Properties Uranium hexafluoride has the chemical formula UF6, which is a light yellow solid powder. Toxic! Radioactive. Specific gravity 4.68. Melting point 64.5~64.8 ℃. Boiling point 56.4 ℃. When the temperature rises or the pressure decreases, it is easy to sublimate into gas (56.4 ℃ at 101.3千帕 or 25 ℃ at 13.1 7千帕). It is chemically active, reacts violently with water, and fluorinated with most organic compounds, which is chemically corrosive. |
Use | Uses uranium hexafluoride is an inorganic metal compound, which can be used for the production of nuclear fuel pellets and the preparation of uranium dioxide. |
