In this paper, studied the refining effects of Sb 2 O 3 and ultraviolet transmitting property of NaCaBSi glasses. These raw materials were weighted according to the (35-x)SiO 2 : 30B 2 O 3 :15Na 2 O:10CaO:10ZnO:xSb 2 O 3 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 (V M ) and refractive index obtained were found to increase with increases in the concentration of Sb 2 O 3 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 Sb 2 O 3 concentrations.
