| MOLYBDENUM HEXAFLUORIDE Usage And Synthesis |
Chemical Properties | liquid | Physical properties | White cubic crystals or colorless volatile liquid; hygroscopic; density 2.54 g/cm3; melts at 17.5°C; boils at 34°C; critical temperature 200°C; critical pressure 46.88 atm; critical volume 226 cm3/mol; reacts with water (hydrolyzed). | Uses | Molybdenum(VI) fluoride plays an important role in the semiconductor industry and the nuclear industry. | Uses | Separation of molybdenum isotopes. | Definition | ChEBI: Molybdenum hexafluoride is a molybdenum halide. | Preparation | Molybdenum hexafluoride is prepared by passing fluorine over molybdenum powder: Mo + 3F2 → MoF6. | Hazard | Strong irritant. | Purification Methods | Purify the hexafluoride by low-temperature trap-to-trap distillation over pre-dried NaF. It is hygroscopic, fumes in moist air and is hydrolysed readily by H2O. [Oppengard et al.
