Plutonium arsenide is a binary inorganic compound of plutonium and arsenic with the formula PuAs.
Fusion of stoichiometric amounts of pure substances in a vacuum or helium atmosphere. [1] The reaction is exothermic:
Passing arsine through heated plutonium hydride:
Plutonium arsenide forms black or dark gray crystals of a cubic system, [2] space group Fm3m, cell parameters a = 0.5855 nm, Z = 4, structure of the NaCl-type. [3]
At high pressure (about 35 GPa), a phase transition occurs to a structure of the CsCl-type. [4]
At a temperature of 129 K, PuAs transforms into a ferromagnetic state. [5]
