Abstract | A study of heat capacity, thermal dilatation, susceptibility to hydrostatic
pressure, permittivity and polarization loops was carried out on NH4HSO4
– porous glass nanocomposites (AHS ? PG) as well as empty glass matrices. The
formation of dendrite clusters of AHS with a size, dcryst, exceeding the pore
size was found. An insignificant anisotropy of thermal expansion of AHS ?
PG showing statistically uniform distribution of AHS with random orientations
of nanocrystallites over the matrix was observed. The effect of internal and
external pressures on thermal properties and permittivity was studied. At the
phase transition P-1 $ Pc, a strongly nonlinear decrease in the entropy DS
2andvolumestrain(DV/V) T2 was observed with decreasing dcryst. The linear
change in temperatures of both phase transitions P-1 $ Pc $ P21/c under
hydrostatic pressure is accompanied by the expansion of the temperature
range of existence of the ferroelectric phase Pc, while this interval narrows as
dcryst decreases. | |
