Raman spectra of rapidly quenched glasses and melts containing large amounts of Li2O

摘要: Abstract Raman spectra were measured of rapidly quenched glasses and the corresponding liquids in binary ternary (pseudobinary) systems composed Li 2 O several glass-forming oxides such as B 3 , P 5 and/or SiO . The fractions various structural units present determined from deconvoluted peaks. Glasses with large amounts discrete ortho-oxoanions pyro-oxoanions. Based on these data identical, although some cases those crystals different. In pseudobinary combining pyro-oxosalts lithium borate, phosphate silicate, non-bridging oxygens preferentially formed at rather than borate or silicate units. This order preference was consistent that acidity liquids.
