Glass nanocomposite (GNCs) samples in the composition [(90-x) Li₂B₄O₇- xBaTiO₃- 10Nb₂O₅] with x = 5, 7.5, 10, 12.5 and 15 (in mol%) were prepared. Rietveld refinement of the data for the reagent grade of the BaTiO₃ revealed that the structure is a tetragonal phase (space group P4mm). The energy dispersive X-Ray (EDX) spectra and scanning electron microscopic (SEM) micrographs exhibit the two phases (BaTiO₃ nanopatricles/clusters phase and residual glass phase) of the GNCs samples. The BaTiO₃ nanoparticles/clusters in the glass matrix were confirmed by transmission electron microscopic (TEM) and Fourier transform infrared (FTIR) studies. The deconvolution of the FTIR spectra of the GNCs samples reveals the presence of BO₃, BO₄, NbO₄ and NbO₆ units. The dielectric results exhibit the ferroelectric of BaTiO₃ nanoparticles/clusters in the GNCs samples at x = 10, 12.5 and 15 mol%. The dielectric constant, dielectric loss and ac conductivity for the GNCs samples as a function of temperature at various frequencies in 120Hz−100 k Hz range have been studied.
