摘要
Lattice dynamical calculations have been carried out in the cubic and orthorhombic phases of the negative thermal expansion compound ZrW2O8. The phonon density of states, thermal expansion, specific heat and bulk modulus have been calculated. The calculations are in good agreement with the available experimental data.
