无碱多元系统磷酸盐玻璃中SiKα、SiKβ谱分析

STUDIES ON Si—O BONDING IN NON-ALAKALINE MULTICOMPONENT BASED PHOSPHATE GLASS BY X-RAY FLUORESCENCE SPECTRA

本文应用日本Rigaku3070X射线荧光光谱仪测定了无碱多元系统磷酸盐玻璃(3.6 SiO_2·1.0Al_2O_3·1.9 MgO·1.0 MgF_2·1.9 CaO·XP_2O_5,X=0,0.25,0.50,0.75和1)的SiKχ谱线,以PW 1404X射线荧光光谱仪测定其SiKβ和SiKβ′谱线,以Pseudo-Voigt函数和统计试验最优化方法作谱处理,其结果表明,以水晶为参比物,SiKα、SiKβ′的化学位移值和△E(SiKβ、SiKβ′)值均与P_2O_5含量有关,随着P_2O_5含量增加,Si—O键增强,桥氧成分增加。

In this paper, the SiKα the SiKβ, and SiKβ' X-ray spectra of glass (3.6 SiO·1.0 Al_2O_3·1.9 MgO·1.0 MgF_2·1.9CaO·XP_2O_5, X=0, 0.25, 0.50, 0.75, 1.0) were measured by REKAKU 3070 and PW1404 X-ray spectrametry. The measured spectra of the glass were fired by statistical optimazation test method. The chemical shift of SiKα and SiKβ' spectra relative to that of quartz decreased with increasing P_2O_5 cotent. These trend indicates that the Si—O bond is strengthened markedly with inereaseing P_2O_5 content.
