摘　　要：利用X射线荧光分析(XRF)、电子探针(EPMA)测试了全氧燃烧浮法玻璃及普通浮法玻璃下表面的渗锡量和渗锡深度分布。结果表明:全氧燃烧浮法玻璃的渗锡量和渗锡深度较高。进一步讨论了全氧燃烧浮法玻璃的渗锡量和渗锡深度高的原因:全氧燃烧浮法玻璃中含水量较高,在锡槽的脱羟基反应加剧了锡槽的污染;结构水增大了离子间距,加速了离子置换;结构水改变了玻璃的结构,锡的扩散阻力变小,增加了锡的渗入量和扩散深度。X-ray fluorescence analysis(XRF)and electron probe(EPMA)were used to test the penetration amount and the diffusion depth of tin on the lower surface of oxy-fuel combustion float glass and air-fuel combustion float glass.The results show that the penetration amount and the diffusion depth of tin in the oxy-fuel combustion float glass are higher.The reason is discussed:the water content in the oxycombustion float glass is high.The dehydroxylation reaction in the tin bath exacerbates the pollution of the tin bath;The structure water increases the ion spacing,thus accelerating ion exchange;Structural water changes the structure of the glass,and the diffusion resistance of tin becomes smaller,increasing the penetration amount and diffusion depth of tin.
