Abstract
In this paper, studied the refining effects of Sb2O3 and ultraviolet transmitting property of NaCaBSi glasses. These raw materials were weighted according to the (35-x)SiO2: 30B2O3:15Na2O:10CaO:10ZnO:xSb2O3 where x=0.0, 0.05,0.1, 0.5, 1.0 and 2.0 mol%. NaCaBSi glasses were obtained by using melt quenching technique and characterized by using density, refractive index, optical absorption spectra and the number of bubbles in glass measure as a function of different concentrations. The density (ρ), molar volume (VM) and refractive index obtained were found to increase with increases in the concentration of Sb2O3 in the glass matrix. The optical absorption spectra of glasses were measured in the wavelength of 200 – 2,000 nm. Number of bubbles in glass decrease when increasing Sb2O3 concentrations.
