Thorium oxyfluoride is an inorganic compound of thorium metal, fluorine, and oxygen with the chemical formula ThOF2.[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]
- [math]\ce{ ThF4 + H2O -> ThOF2 + 2HF }[/math]
- Reaction of thorium tetrafluoride with thorium dioxide at 600 °C:
- [math]\ce{ ThF4 + ThO2 -> 2ThOF2 }[/math]
Physical properties
The compound forms white, insoluble amorphous powder.[6]
Uses
The compound is used as a protective coating on reflective surfaces.[7]
