Structure and properties of lead tungstate phosphate glasses
Original language description
Glasses in the ternary system PbO-WO3-P2O5 with {= 50 mol% P2O5 were prepared and their basic characteristic parameters were determined. The structures of three compositional series (100-x)[0.5PbO-0.5P(2)O(5).]-xWO(3), 50PbO- yWO(3)-(50-y)P2O5 and (50-z)PbO-zWO(3)-50P(2)O(5) were investigated by Raman and P-31 NMR spectroscopies. Their glass transition temperatures increase with increasing WO3 content. P-31 MAS NMR spectra of the glasses indicate a shortening of phosphate chains with the incorporation of tungstate structural units. Most of the studied glasses contain tungsten atoms in octahedral WO6 units, but in glasses with a high PbO content and a low P2O5 content the formation of WO4 units cannot be excluded. Clustering of WO6 units by the formation of W-O-W bonds takes place in glasses with a high WO3 content as observed from their Raman spectra.
