Аннотация:
Heat capacity, thermal dilatation, sensitivity to pressure and permittivity of NH4HSO4
embedded into glass matrices with a pore size of 320 nm and 46nm
were studied. Large difference in the thermal expansion of both glass and
ferroelectric leads to a “clamped” state of NH4HSO4 in nanocomposites and to
the phase transition temperatures change. The restricted geometry does not
effect on the order of successive transformations in NH4HSO4 but is
accompanied by a significant reduction in entropy of phase transitions. The
behavior of DTA-signal and permittivity show the expansion of the
temperature range of the ferroelectric phase under hydrostatic pressure.
