Vitreous systems based on antimony oxide Sb2O3 have been investigated. The limits for glass formation are reported in the Sb2O3-CdCl2-SrCl2 ternary system, and in the Sb2O3-SrCl2-(0.5CdCl(2)+0.5ZnCl(2)) pseudo ternary system. Amorphous state is confirmed by XRD patterns. Thermal measurements implemented by differential scanning calorimetry show that Tg is above 300 degrees C. As a general trend. Tg increases with chloride content. These glasses have an extended transmission in the mid-infrared spectrum with a refractive index larger than 2. The influence of the CdCl2/Sb2O3 substitution on the physical properties has been studied in the (90 - x)Sb2O3-xCdCl(2)-10SrCl(2) system: thermal expansion, Vickers microhardness, Young and bulk modulus decrease as cadmium concentration increases. An inverse dependence is observed for shear modulus. This behaviour is discussed in relation to structural hypothesis.
