The article presents the results of measurements of the electrical resistance of α-Zr samples under shock compression conditions. Experiments with shock waves were accompanied by modeling the thermodynamic history of compression of samples and the synchronous history of changes in their electrical properties. Modeling of the electrophysical properties of α-Zr with its changes in volume and temperature under shock compression was carried out within the framework of a hydrocode containing equations of state and a semi-empirical zirconium resistivity model taking into account the saturation temperature. The free parameters of the semi-empirical model of the electrical resistivity of zirconium are determined. These parameters were also used to restore the temperature-baric dependence of the thermal conductivity of α-Zr at high pressures and temperatures. Keywords: zirconium, shock waves, equations of state, electrical resistivity, resistivity saturation, thermal conductivity, high pressures.
