New heavy metal oxide glasses involving Sb_2O_3 have been investigated. By using classical routes (melting-casting), glasses synthesized in silica crucibles were obtained in the combination of ternary systems Sb_2O_3-M_2CO_3-MoO_3 (M = Li and K). Characteristic temperatures such as glass transition T_{g}, and onset of the crystallization T_{x}, have been measured using differential scanning calorimeter. Ultrasonic velocities were measured by using pulse echo method to determine the elastics parameters, such as elastic modules (E, G, K, L). Other physical properties were measured, such as density and optical transmission window in far infrared spectra using KBr pellets. Influence of composition on these physico-chemical properties is discussed and correlated to the glass structure.
