Abstract: The temperature dependences of the dielectric spectra of Ag$_2$S nanocrystallites synthesized inside the channels of nanoporous glasses NPG-17 with an average diameter of filamentous pores of 17 nm are studied. The macroscopic mechanism for the occurrence of the frequency dependence of the electrical response of a nanoporous structure NPG+Ag$_2$S is proposed. Formation of the model of mechanism is based superionic phase transition in Ag$_2$S nanocrystallites fixed inside the channels of nanoporous glass is discussed.
