摘要

Glass samples of the barium phosphosilicate 20SiO_2-7.5K_2O-7.5Na_2O-xBaO-(65-x)P_2O_5 (x = 2.5, 5.0, 7.5, 10.0) are prepared by conventional melt-quench technique. The density and molar volume of glasses were determined in order to explore their structural properties. Results show that molar volume decreases linearly with increase in mol% of BaO. The metallization parameter values of the prepared glasses are found to be less than one and thus exhibit insulating behaviour. The physical parameters like refractive index, dielectric constant, reflection loss, molar refractivity and molar electron polarizability are also studied. Dielectric constant, refractive index, molar refractivity and molar polarizability decreases with increase in mol% of BaO. The maximum values of these parameters are found with 2.5 mol% of BaO.
