Effect of glasses melting temperature to bubbles size on Sb2O3 doped glasses

Abstract

The physical and optical properties of the glasses system in compositions (35-x)SiO2 : 30B2O3 : 15Na2O :10CaO :10ZnO : xSb2O3 where x = 0.00, 0.05, 0.10, 0.50, 1.00 and 2.00 mol% were synthesized by using the melt-quenching technique and compared temperatures of 1000, 1100, 1200, 1300 and 1400 ºC. The results show that the density (ρ), molar volume (VM ) and refractive index (n) of glasses were tended to increase with increasing concentration of Sb2O3. On the opposite, when increasing melting temperature the result of the density (ρ), molar volume (VM ) and refractive index (n) of glasses were tended to decrease. The UV-Vis-NIR spectra of glasses were measured at the wavelength of 200-2000 nm. The number of bubbles in glasses tends to decrease with increasing concentration of Sb2O3 and melting temperature also.
