hexafluoride A hexafluoride is a chemical compound with the general formula QXnF6, QXnF6m−, or QXnF6m+. Many molecules fit this formula. An important hexafluoride is hexafluorosilicic acid (H2SiF6), which is a byproduct of the mining of phosphate rock. In t ...

Synthesis

The synthesis of via the reaction : was attempted in 1945, but the attempt was unsuccessful. The boiling point was predicted to be about −40 °C. was probably successfully synthesised via the same reaction in 1960 with the more stable isotope , where a volatile polonium fluoride was produced, but it was not fully characterized before it underwent

radiolysis Radiolysis is the dissociation of molecules by ionizing radiation. It is the cleavage of one or several chemical bonds resulting from exposure to high-energy flux. The radiation in this context is associated with ionizing radiation; radiolysis is ...

and decomposed to polonium tetrafluoride.
