DIELECTRIC PROPERTIES OF LI2O-B2O3-AL2O3 GLASS SYSTEM

ABSTRACT The ion conducting glasses 35Li2O: (65-X) B2O3: X Al2O3 have been prepared with various compositions (where X = 0,5,10,15,20) by using melt quenching technique. The electrical conductivity and dielectric parameters of glasses were analyzed by LCR impedance analyzed in the frequency range (100Hz-1MHz) at different temperatures (323K-623K). It has been observed that the electrical conductivity of glass increases with increase in mole percent of aluminum oxide. The dielectric constants and dielectric modulus are reported and described dielectric relaxation mechanism.
