摘要:

采用透射电镜(TEM),电子探针-能谱(EPMA-EDS)组合等仪器对不同年代景德镇低温黄釉瓷片的组成、结构进行了分析.结果表明:除民国样品外,历代黄釉的化学组成无很大变化,且均是以铁着色,不同的是在成化、弘治、正德和民国时期的样品中发现存在底釉,在民国样品表面黄釉中则发现有锑、锡元素存在;首次发现民国低温黄釉表面有Pb2Fe0.5Sb1.5O6.5晶体析出.

Abstract:

TEM and EPMA-EDS were used to analyze the composition and structure of(Jingdezhen's) low temperature yellow-glaze samples since the Ming and Qing dynasty.Results indicate that the compositions are little different except that of early Republic period samples;and the samples which came from the Hongzhi,Chenghua,Zhengde and early Republic period have engobe.At the same time,just in the sample of early Republic period antimony and tin elements were used as colorant.It is first found that the surface of early Republic period samples contains some crystal Pb_2Fe_(0.5)Sb_(1.5)O_(6.5) by TEM.
