Abstract: Li2O-MgO-B2O3:TiO2 glasses were crystallized at three different temperatures. The samples were characterized by scanning electron microscopy and differential scanning calorimetry. Various physical properties viz., optical (optical absorption, IR spectra and thermoluminescence), magnetic (magnetic susceptibility and ESR spectra) have been studied as a function of temperature of crystallization. The investigation is further extended to the dielectric properties viz., dielectric constant, loss and a.c. conductivity over a moderately wide range of frequency and temperature. The analysis of these results indicated a considerable increase in the electrical insulating strength of the samples due to crystallization.
