Potential barrier in a two-layer porous structure based on ZrO2 and Ca6H2O19Si6, depending on filling of the pores with electrolyte (H2O)

. In this paper, current-voltage characteristics of a two-phase disperse system Ca6H2O19Si6 + ZrO2 as functions of filling of the pores with electrolyte (H2O) have been investigated. It has been shown that presence of free water in the pores of the Ca6H2O19Si6 + ZrO2 structure maximizes the current through this structure as well as induces blurring of the potential barrier in it due to the appearance of charge carriers (mobile ions), capable of moving through the entire two-layer disperse system, in the free water layer. Outflow of the free water leads not only to the disappearance of an additional channel for free movement of mobile ions through the entire structure, but also to an increase in the ion concentration in the diffuse layer. As a result, the efficiency of the potential barrier at the boundary between the layers of the structure as a rectifying element increases.
