The parameters of the paired 4-parametric interatomic potential of Mie-Lennard-Jones for bcc-W were obtained. The equation of state, baric and size dependencies of the coefficient of thermal volume expansion, elastic modulus, specific isobaric heat capacity and also specific surface energy of tungsten macro- and nano-crystal were calculated using obtained parameters of interatomic potential. The pressure derivatives of these dependencies were studied also.
