HIGH-TEMPERATURE CONSOLIDATION AS A STRUCTURE CONTROL METHOD OF THE NANOPOROUS GLASSES

Nanoporous glass is a matrix for composite optical materials, in which, by impregnating various activators, it is possible to initiate the appearance of properties that are uncharacteristic for the composite materials. In this case, the main parameter of the structure of nanoporous glass is porosity, which can be controlled by the method of high-temperature consolidation. In this work, we have studied the effect of temperature consolidation on the structure of porous glass.

Импедансметрия нанокристаллитов Ag-=SUB=-2-=/SUB=-S, внедренных в нанопористые стекла

The temperature dependences of the dielectric spectra of Ag2S 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+Ag2S is proposed. Formation of the model of mechanism is based superionic phase transition in Ag2S nanocrystallites fixed inside the channels of nanoporous glass is discussed.
