Plutonium silicide is a binary inorganic compound of plutonium and silicon with the chemical formula PuSi.[2][3][4] The compound forms gray crystals.

Synthesis

[edit]

Reaction of plutonium dioxide and silicon carbide:

Reaction of plutonium trifluoride with silicon:

Physical properties

[edit]

Plutonium silicide forms gray crystals of orthorhombic crystal system, space group Pnma, 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 a ferromagnetic transition.[5]

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
