The glass system 40B(2)O(3)-20SiO(2)-9Na(2)O-1Fe(2)O(3)-(30-x)Bi2O3-xMoO(3), x = (0, 5, 10, 12.5 and 15 mol%) was prepared and analyzed by using X-ray diffraction, IR spectroscopy, density, differential thermal analysis (DTA), optical properties and mechanical properties. The structural variations due to the increase of the MoO4 at the expense of the BiO3 structural unit increase the ultrasonic velocity and the elastic moduli along with a decrease of the density. The increase of the glass transition temperature, T-g, according to DTA confirmed this behavior. The values of the optical band gap E (g) and refractive index have been determined and it was found that these parameters are sensitive to the increase of MoO3 content.
