Abstract
Antimony silicate glasses, of general formula xSb(2)O(3)center dot (1 - x)SiO2 (0.1 <= x <= 0.78), have been prepared by melt-quenching and their structures studied using Si-29 MAS NMR spectroscopy, Sb-121 Mossbauer spectroscopy and Raman spectroscopy. Oxidation during melting gives rise to Sb5+ in concentrations, which increase linearly with x to give a value of similar to 10% when x=0.78. Sb-121 Mossbauer spectra show Mossbauer shifts and quadrupole splittings consistent with Sb3+ in a [:SbO3] trigonal pyramid, similar to that in crystalline Sb2O3. A broad band in the Raman spectrum at similar to 410 cm(-1) is due to the vibrations of such a unit. The dependence of the silicon Q '' speciation on x can be interpreted by the formation of Sb-O-Sb links possibly to form rings of 4 [:SbO3] units such as are found in valentinite.
