Abstract
The region of a high electrical conductivity of lithium hydride is experimentally determined in the pressure range 100–150 GPa and the temperature range 2000–3000 K of multiple shock compression. This result is used to construct thermodynamic potentials for the two polymorphic modifications of lithium hydride (B1, B2), and these potentials make it possible to calculate its thermophysical properties in the shock pressure range 80–1200 GPa. The calculated and experimental results are analyzed to determine the B1 ↔ B2 equilibrium line for the polymorphic modifications of lithium hydride at pressures up to 300 GPa and temperatures up to 2000 K.
