摘要：

An analytical function of pressure on specific volume and internal energy is developed for niobium. This function allows one to adequately describe the thermodynamic properties of this metal in a wide range of densities and pressures. A comparison of the calculated shock adiabat with experimental data at high dynamic pressures is made. The equation of state proposed for niobium can be used to model physical phenomena at high energy densities.
