Investigation of the system AgBr-AgI optical materials volt-ampere characteristics

IR light guides based on crystals and ceramics of the AgBr-AgI system are transparent in mid-infrared range from 2 to 25 μm, which is demand for thermal imaging, laser technology spectroscopy. High photo- radiation resistance makes these materials particularly attractive. For design optical equipment, information needed electrical properties material, most fully characterized by current-voltage characteristic (VAC). In this work, dependence VAC studied compositions 5 80 mol.% AgI composition material temperature 298-453 K. It has been established that an increase iodine content crystalline systems leads a decrease conductivity. The values specific conductivity under equal conditions (the same applied voltage) two three orders magnitude higher than crystals. at level solid electrolytes. At β-AgI-α-AgI phase transition systems, jump observed, explained transition. Keywords: Solid solutions system, characteristic,
