Thorium oxyfluoride is an inorganic compound of thorium metal, fluorine, and oxygen with the chemical formula ThOF
2.[1][2][3]

Synthesis

  • Thorium oxyfluoride can be prepared from partial hydrolysis of thorium tetrafluoride in moist air at elevated temperatures, about 1000 °C.[4][5]
ThF4 + H2O → ThOF2 + 2 HF
ThF4 + ThO2 → 2 ThOF2

Physical properties

The compound forms white, insoluble amorphous powder.[6]

Uses

The compound is used as a protective coating on reflective surfaces.[7]
