【摘要】 本工作研究硫结合入硼硅酸盐玻璃的结构,结构性质可为提高硫的包容量提供理论依据。实验收集了多种晶体标准的硫XANES谱图,通过比较玻璃中硫的XANES谱图与标准物质中硫的XANES谱图,得出在硼硅酸盐玻璃中,硫以硫酸根形式存在,无明显可观测到的还原性硫存在。硫酸根被网络调节剂阳离子所环绕。更多还原

【Abstract】 The structural aspects of sulfur incorporation in borosilicate glasses were studied in the paper.Understanding of the structural aspects may provide theoretical basis for increasing the sulfur solubility in the glass.Sulfur XANES(X-ray absorption near-edge spectroscopy) spectra of several crystalline standards were collected.By comparing sulfur XANES spectra in the glass and those in crystalline standards,it can be concluded that the sulfur is present as SO2-4 and no reduced sulfur is observed in the borosilicate glass.The results also indicate that SO2-4 is surrounded by network modifying cations.更多还原
