Morphology and Structural Studies of Tungsten Doped Arsenic Tellurite Glass and Glass-Ceramics
The comparative study on structural, thermal, and spectroscopic properties of a new transparent tungsten doped arsenic tellurite glass and glass-ceramic system with composition xWO3 + (30 – x)As2O3 + 70TeO2 (where x = 10, 20, 30 mol %) has been synthesized using conventional melt quenching and conventional heat treatment method. Various characteristics like physical, optical, structural, thermal and ESR of both the systems (glass and glass-ceramic) were studied. The physical parameters such as density of both glass and glass-ceramic systems shows increasing trend from 6.515–6.996 and 6.993–7.748 g/cm3. The thermal parameter glass transition temperature (Tg) of both glass and glass-ceramic samples is increased linearly from 331–353 and 336–367°C respectively. Structural analysis reveals that the present glass and glass-ceramic systems have TeO4, TeO3 + 1 and TeO3 and WO6 and/or WO4 and AsO3 units as fundamental structural units. The SEM and EDS spectra of glass-ceramic system shows that the particles agglomerates in the form of tetrahedron and strips like takes place and the size of the particles found to be in the range of 56 to 236 nm.
