IMPEDANCE OF DISTRIBUTED STRUCTURES BASED ON SOLID ELECTROLYTES

In the last few years, the science of superionic conductors, or solid- state ionics, came into common use. It proved advantageous to design c ertain devices, such as sensors and generators of gases, power sources , etc., on the basis of superionic conductors. Unlike semiconductors, there is no need to use superionic conductors in the form of single cr ystals. It is compressed powders, ceramics, and composites on the basi s of polymeric matrixes that are used in these devices. Therefore, it is quite clear why solid-state ionics are interested in the distribute d structures. The latter can incorporate composite materials combined from several substances, as well as compressed powders and ceramics, i n which impurities can be segregated at the boundaries of crystallites ; ion transport can also be hampered by different orientations of crys tallites.
