摘 要：<正> The chemical compositions,microstruc-tures and some properties of the West HanDynasty PbO·BaO·SiO2 glass clothes flakesexcavated from a tomb at Yang Zhou,JiangsuProvince were investigated.These glassflakes consist of a clear glass core and anouter layer with different thicknesses beingloose,grey and opaque due to the corrosionof the rotten dead body and moist surround-ings during a long period of about twothousand years.The glass core and the outerlayer are quite different in composition.Itis found that the thermal expansioncoefficient of the glass core is α=64×10-7/℃（9-400℃）,the transformation point Tg=476℃,the softening temperature TS=520℃,therefractive index nD=1.6389,and the micro-hardness HV=438kg/mm2.Results obtained bymeans of high resolution electron microscopy,X-ray diffraction,Raman spectrum,hightemperature microscopy and differentialthermal analysis are discussed.
