广西合浦地区出土汉代古玻璃的质子激发X荧光分析

采用改进的外束质子激发x射线荧光、电感耦合等离子体原子发射光谱分析等技术，对广西合浦地区出土的一批汉代古玻璃样品的化学成分和结构特性等进行了检测。结果表明：两汉时期，合浦地区的古代玻璃存在K2O—SiO2、PbO-BaO-SiO2、PbO—SiO2、Na2O-K2O-PbO-SiO2、（Na2O）K2O-CaO—SiO2等多种类型，但绝大多数为K2O—SiO2玻璃。表面风化可引起K2O-SiO2玻璃表面K2O等助熔剂的流失和富硅层的形成。综合化学成分以及器型特征，认为我国汉代K2O—SiO2玻璃制造技术可

abstract {Combining the modified external-beam proton induced X-ray emission (PIXE), inductively coupled plasma atomic emission spectrometry (ICP-AES) and other techniques, the chemical compositions, structures and other properties of some ancient glass samples of the Han Dynasty, which were unearthed from Hepu county, Guangxi, were determined. These glass samples can be classified to several glass systems, such as K₂O-SiO₂, PbO-BaO -SiO₂, PbO-SiO₂, Na₂O-K₂O-PbO -SiO₂ and (Na₂O)K₂O-CaO-SiO₂. But most of the samples belong to K₂O-SiO₂ system glass. Due to the surface corrosion, the flux K₂O in the surface of the K₂O-SiO₂ glass was lost, but with the relative enrichment of the SiO₂. Based on the characteristics of chemical composition and appearance of these samples, it is thought that, during the Han Dynasty, the making technique of the K₂O-SiO₂ glass in China was influenced by the technique related to the PbO-BaO-SiO₂ glass from abroad.}
