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]
