To investigate the chemical components and microstructure of Nengchi Bajin ashes which are adjuvant material in the refining of Tibetan medicine gTSo thal, in order to explore the material basis of the refining of gTSo thal.
Scanning electron microscope-energy dispersive spectrometer (SEM-EDX) and X-ray diffraction (XRD) were used to measure the Nengchi Bajin ashes.
SEM-EDX analysis show that except of themselves elements of Nengchi Bajin ashes, Nengchi Bajin ashes contain the major elements, such as S, O, C and so on, also contain small amount other elements. XRD analysis show that the structures are AuPb2, PbO (tetragonal and orthorhombic) and Pb in gold ash, Ag2S and PbO in silver ash, Cu1.98 (Zn0.73 Fe0.29)Sn0.99 S4, CuS, SiO2, NaCu2S2 and Ca (Fe(+2), Mg) (CO3)2 in bronze ash, Cu7S4 (orthorhombic and monoclinic) and CuO in red copper ash, Cu7 S4, PbS, ZnS, CaCO3and NaCu2S2 in brass ash, FeS, Fe+2 Fe(2+3)O4 and SiO2 in iron ash, SnS and SiO2 tin ash, PbS, PbSO4 and SnS2 in lead ash.
We have acquired the datum of elements and microstructure of Nengchi Bajin ashes by SEM-EDX and XRD techniques, and that is benefit to explore the material basis of refining gTSo thal.
研究藏药七十味珍珠丸炼制中辅料能赤八金灰的化学成分和微观结构，以探讨七十味珍珠丸炼制的物质基础。
采用扫描电子显微镜-能谱仪（SEM-EDX）和X射线衍射（XRD）对能赤八金灰进行测定。
SEM-EDX分析表明，能赤八金灰除自身元素外，含有S、O、C等主要元素，还含有少量其他元素。XRD分析表明，金灰中的结构为AuPb₂、PbO（四方晶系和正交晶系）和Pb，银灰中的结构为Ag₂S和PbO，青铜灰中的结构为Cu₁.₉₈(Zn₀.₇₃Fe₀.₂₉)Sn₀.₉₉S₄、CuS、SiO₂、NaCu₂S₂和Ca(Fe(+2),Mg)(CO₃)₂，红铜灰中的结构为Cu₇S₄（正交晶系和单斜晶系）和CuO，黄铜灰中的结构为Cu₇S₄、PbS、ZnS、CaCO₃和NaCu₂S₂，铁灰中的结构为FeS、Fe₂Fe₃O₄和SiO₂，锡灰中的结构为SnS和SiO₂，铅灰中的结构为PbS、PbSO₄和SnS₂。
通过SEM-EDX和XRD技术获得了能赤八金灰的元素和微观结构数据，有利于探讨七十味珍珠丸炼制的物质基础。
