Chemical compound
Thorium oxyfluoride is an inorganic compound of thorium metal, fluorine, and oxygen with the chemical formula ThOF
2.[1][2][3]
- 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
[edit]The compound forms white, insoluble amorphous powder.[6]
The compound is used as a protective coating on reflective surfaces.[7]
