摘要：
It is assumed that the high conductivity of uranyl orthophosphate tetrahydrate derives from a system of hydrogen bonds in the two-dimensional water network. The influence of the degree of hydration of the acid uranyl orthophosphate on the conductivity and character of conduction was studied to confirm this assumption. Polycrystalline samples of uranyl orthophosphate tetrahydrate UO2 HPO4.4H2O (I) and monohydrate UO2HPO4.H2O (II) were pressed with a pressure of 400 MPa. The conductivities of I and II were measured with ac at frequencies of 100 Hz to 50 kHz and under isothermal conditions; the temperature range was from 290 to 373°K.
