摘要: Electrical properties of two-phase mixtures copper(I) bromidewith titanium dioxide are investigated by impedance spectroscopy coupledwith X-ray diffraction and scanning electron microscopy. An increase ofconductivity more than an order magnitude with respect to purecopper(I) bromide is detected in the extrinsic domain. The results can beinterpreted framework brick-layer space charge model. Theimportance OH groups on surface titania particles as preferredsites for internal adsorption copper ions confirmed. A maximum effecton conductivity revealed about 15 mol% second phase andrelated microstructure composites.
