Objective: To investigate the chemical components and microstructures of Nengchi Bakuang ashes(mica ash and seven minerals ashes) which are adjuvant material in the refining of Tibetan medicine Zuotai(gTSo thal),in order to explore the material basis of the refining of Zuotai. Methods: Scanning electron microscope-energy dispersive spectrometer(SEM-EDX) and X-ray diffraction(XRD) were used to measure Nengchi Bakuang ashes. Results: SEM-EDX analysis show that the main elements in mica ash are C,O,Mg,Al,Si,K and Fe,also contain some kinds minor elements,such as F,Na,P,S,Cl,Ca,Ti,Cu,Zn,As,et al;that the main elements in seven minerals ashes are C,O,S,K,Fe and Na,also contain some kinds minor elements,such as Al,Si,Cl,Ca,Cu,Zn,As.XRD analysis show that the substance forms in mica ash are K(Mg,Fe)₃(Al,Fe)Si₃O₁₀(OH,F)₂(monoclinic),KMg₃Si₃AlO₁₀(F,OH)₂(monoclinic),Mg₂SiO₄(monoclinic),SiO₂(hexagonal),(Na_0.4Ca_0.6)Al_1.6Si_2.4O₈(triclinic),FeS(hexagonal),et al;that the substance forms in seven mineral ashes are SiO₂(hexagonal),CaCO₃(rhombohedral),K₂Ca(SO₄)₂ H₂O(monoclinic),FeAs₂(orthorhombic) FeAs(orthorhombic),Fe₂As(tetragonal),KCl(cubic),Cu₂S(cubic),SiO₂(hexagonal),AsFe(orthorhombic) and so on. Conclusion: The present research have acquired the datum of elements and microstructure of Nengchi Bakuang ashes by SEM-EDX and XRD techniques,and that is benefit to explore the material basis of refining Zuotai.
