Abstract: Temperature evolution of small angle neutron scattering on nanocomposites on base of porous alkali borosilicate glasses filled by sodium nitrite has been studied. The gyration radius (33-35 nm) of NaNO2 nanoparticles has been determined. It is shown that on heating and passing through the temperature of ferroelectric phase transitions the density of nanostructured sodium nitrite decreases. [ABSTRACT FROM AUTHOR]
