“…The density (ρ) values of the samples, measured at 25°C (Table ), show that ρ increases, as the NaPO 3 content is replaced by LiCl. This can indicate the formation of a denser glass structure, which is in agreement with the work of Assem et al, which acknowledged that when chloride ions are structurally inserted in the glass network, filling the vacant sites of interstices positions, the density increases by decreasing the free volume. Besides the density values, Table also shows the molar volume of the prepared samples.…”

Glasses with molar composition 2xLiCl–(40−x)Na2O–(40−x)P2O5–20Li2O, where 0 ≤ 2x≤7 (mol%), were prepared by the melt‐quenching method. The synthesized glasses were characterized by X‐ray diffraction, which confirmed their amorphous nature. The glass transition temperature and crystallization temperature of the samples were determined by differential thermal analysis. The density of the samples was measure using Archimedes principle, and the structural analysis was further investigated using infrared and Raman spectroscopy. The dc conductivity of the samples was investigated, along with their dielectric properties using impedance spectroscopy, in the frequency range 100 Hz to 1 MHz, which showed a maximum of conductivity for the sample with 7 mol% of LiCl. The results were correlated to the increased number of lithium ions and to the chloride ions which can either form P–Cl bonds or occupy the interstitial sites of the glass network.

“…Band at 1020 cm -1 is due to the symmetric stretching vibrations of the (PO 4 3-) tetrahedra (P-O-ionic group) [27]. The fundamental band at 980 cm -1 is observed in case of all samples and it is an indication of phosphate ions in p state, exist in tetrahedral symmetry and the bands in 950 cm -1 region are due to the asymmetric stretching vibrations of P-O-P groups [28]. Bands at 720 and 730 cm -1 are due to symmetric vibration the P-O-P chains.…”

ABSTRACT:A series of 20CaO-10ZnO-59.9P 2 O 5 -10Pb 3 O 4 -0.1x, (x= V 2 O 5 , Cr 2 O 3 , MnO and CuO) glasses was prepared by melt quench technique. Spectroscopic properties of the prepared glass systems were investigated using XRay diffraction, Ultra-Violet (UV) spectroscopy, Differential Scanning Calorimetry (DSC), Electron Paramagnetic Resonance (EPR -X band), Fourier Transform Infra Red (FTIR) spectroscopy and Raman spectroscopy. Present investigation is useful to study the effect of glass composition on the optical, thermal, physical properties and symmetry of the prepared glasses. Various physical properties for all the glasses were measured. X-ray diffraction of glass samples was carried to check its amorphous nature. From EPR spectra, the spin-Hamiltonian parameters were calculated and these parameters were influenced by the change in glass composition for different transition metal ions. The FTIR spectral investigations of glasses revealed characteristic vibrations of PO 4 3-units. The Raman spectra of all glass samples have displayed different spectral bands, and intensity of these bands. The results showed that the network structure of these glass samples is found to be change from glass to glass.
