Plutonium silicide is a binaryinorganic compound ofplutonium andsilicon with the chemical formula PuSi.^[2][3][4] The compound forms gray crystals.

Reaction ofplutonium dioxide andsilicon carbide:

${\displaystyle \mathsf{P}\mathsf{u}{\mathsf{O}}_{\mathsf{2}}\mathsf{+}\mathsf{S}\mathsf{i}\mathsf{C}\stackrel{\mathsf{T}}{\to }\mathsf{P}\mathsf{u}\mathsf{S}\mathsf{i}\mathsf{+}\mathsf{C}{\mathsf{O}}_{\mathsf{2}}\uparrow }$

Reaction ofplutonium trifluoride with silicon:

${\displaystyle \mathsf{4}\mathsf{P}\mathsf{u}{\mathsf{F}}_{\mathsf{3}}\mathsf{+}\mathsf{7}\mathsf{S}\mathsf{i}\stackrel{\mathsf{T}}{\to }\mathsf{4}\mathsf{P}\mathsf{u}\mathsf{S}\mathsf{i}\mathsf{+}\mathsf{3}\mathsf{S}\mathsf{i}{\mathsf{F}}_{\mathsf{4}}}$

Plutonium silicide forms gray crystals oforthorhombic crystal system, space groupPnma, cell parameters: a = 0.7933 nm, b = 0.3847 nm, c = 0.5727 nm, Z = 4, TiSi type structure.

At a temperature of 72 K, plutonium silicide undergoes aferromagnetic transition.^[5]
