NMR and dielectric studies of NaNO2 loaded into an SBA-15 mesoporous matrix are reported. The spin-lattice relaxation rate and the 23Na NMR line shift, as well as the permittivity, were measured within a broad temperature interval including the ferroelectric phase transition in NaNO2. The phase transition temperature of sodium nitrite in as-prepared samples was shown to differ substantially from that characteristic of a bulk crystal. The permittivity grows strongly in the vicinity of the phase transition. Heating a sample causes the properties of NaNO2 embedded in pores to gradually approach those of bulk crystals.
