Abstract
The influence of Cs 2O content on MoO 3CuO-PbO 2 vitreous system has been investigated. The obtained samples labeled as: S1, S2, S3, and S4 respectively, with respect to Cs 2O content were synthesized by the melt-quenching method. The Cs 2O addition up to S3 sample increases the hardness, density and LAC values from 3.23 to 3.52 GPa, 6.553 to 6.906 g/cm 3 and 588.50 to 610.39 cm −1 respectively, and decrease the V m, HVL and MFP values. For S4 sample, reverse trends were observed. X-ray diffraction pattern reveals the presence of amorphous structure in the S1-S3 samples but further Cs 2 O addition, S4 sample leading to the formation of multiple crystalline phases. The FTIR spectra indicated that the structural unit distributions of the glasses network: [PbO n], [CuOn], and molybdate species [MoO 6], [MoO 4] 2− and [Mo 2O 7] 2− depends on the Cs 2O content. The resonance line intensity of the Cu 2+ ions gradually diminishes by addition of Cs 2O.
