Thorium trichloride is a binary inorganic compound of thorium metal and chlorine with the chemical formula ThCl
3.[1][2][3]
Synthesis
The compound can be prepared by reducing thorium tetrachloride at 800°C:[4]
- 3Th + ThCl
4 → 4ThCl
3
Also a reaction of both elements:[5]
- 2Th + 3Cl
2 → 2ThCl
3
Other reactions are also known.[6]
Physical properties
The compound forms crystals of the uranium trichloride crystal system.
Chemical properties
Above 630 °C thorium trichloride dissociates into the dichloride and tetrachloride.
Uses
Thorium trichloride is supposed[clarification needed] to be used in a dual fluid reactor as reactor fuel.[7]
