The bulk properties, including lattice constant, bulk modulus and its pressure derivative are obtained. The elastic constants and their pressure dependence are calculated using total energy variation with strain technique. We derived the bulk modulus, shear modulus, Young’s modulus and Poisson’s ratio for ideal polycrystalline XP aggregates. We estimated the Debye temperature of XP compounds from the average sound velocity. Our results are in reasonable agreement with the available theoretical and experimental data. 2009-08-02T08:45:25Z 2009-08-02T08:45:25Z 2009-04 Article Computational Materials Science, vol.45 (2), 2009, pages 474-479 0927-0256 http://www.sciencedirect.com/science/journal/09270256 http://hdl.handle.net/123456789/6665 en Elsevier B.V.
