Thorium trichloride is a binary inorganic compound of thorium metal and chlorine with the chemical formula ThCl3.[1][2][3]
Synthesis
[edit]The compound can be prepared by reducing thorium tetrachloride at 800°C:[4]
- 3Th + ThCl4 → 4ThCl3
Also a reaction of both elements:[5]
- 2Th + 3Cl2 → 2ThCl3
Other reactions are also known.[6]
Physical properties
[edit]The compound forms crystals of the uranium trichloride crystal system.
Chemical properties
[edit]Above 630 °C thorium trichloride dissociates into the dichloride and tetrachloride.
Uses
[edit]Thorium trichloride is supposed[clarification needed] to be used in a dual fluid reactor as reactor fuel.[7]
