STRUCTURE AND PROPERTIES OF TeO2- CONTAINING BORATE GLASSES
Keywords:
TeO2, borate glass, thermal properties, molar volume, XANES, trigonal bipyramidsAbstract
The structure and properties of TeO2-containing B2O3-Al2O3-ZnO glasses were investigated. Theglass transition temperature (Tg) decreases monotonically with an increase in the amount of TeO2.The density also increases linearly with an increasing amount of TeO2. XANES spectra indicate thatTeO4 trigonal bipyramids structural units are present uniformly in these glasses and this structuralunit shares corners with BO3 and BO4 structural units. This reveals that TeO2 is incorporated intoborate structure as a glass former.
