无铅金红玻璃的研究

Study of Lead-Free Red Glass

以钠钙硅酸盐代替铅硅酸盐为基础成分,掺杂金制备了金红玻璃。用分光光度计测量了的透过率曲线。用扫描电镜观察了玻璃表面形貌及金颗粒尺小。结果表明：玻璃的吸收峯为540nm,金颗粒尺寸为40~80 nm,玻璃呈玫瑰红色。这种无铅玻璃减少铅的污桨,降低了成本。

Soda-lime silicate instead of lead silicate was doped with gold to fabricate red glass. Spectro- photometer was used to measure the glass transmittance curves. The glass surface morphology and gold particle size were observed by scanning electron microscope. Results show that the absorption peak was at 540 nm, gold particle size was within 40-80 nm, and a red rose color appeared. This kind of lead free red glass can reduce the lead pollution and cut the cost.
