Density of Na2O-(3-x)SiO2-xGeO2 glasses related to structure
Materials Research Bulletin 39(2004)217-222，-0001，（）：
In order to elucidate the short-rang order structure in the ternary system Na2O-(3-x) SiO2-xGeO2 we employ in this study a quantitative description to determine the molar ratios of Na2O to SiO2 (RSi) and Na2O to GeO2 (RGe) in sodium germanosilicates. The calculated results show that the sodium oxide has no preference for the silicate or the germanate part of the network and there are the same short-rang order units in various Na2O-(3-x) SiO2-xGeO2 glasses. The Raman spectra also confirm the calculated results.
