Abstract:-The mechanical and thermal properties of plutonium monochalcogenides and
monopnictides are calculated using elastic constants and sound velocities, those have been
derived from two body inter- ionic potential theory. We have calculated the Young’s modulus (E),
Poisson’s ratio (ν), anisotropy factors (A), bulk modulus to shear modulus ratio (B/G) for these
compounds. The calculated values of Poisson’s ratio show that the ionic contributions to the
atomic bonding are dominant for these compounds. The B/G ratio indicates that, only PuS will
behave in the brittle manner and other compounds will show the ductile nature. We have also
calculated the sound velocities, Debye temperature (θD), Grüneisen parameter (ς), and lattice heat
capacities (β) for these compounds.
