| 摘 要： | Feldspar and Pb（NO3）2 were mixed and reacted at T=380℃ to synthesize Pb-feldspar. In the XRD （X-ray diffraction） pattern of the product, the d values （crystal lattice spacing） of the five peaks are 0.654, 0.342, 0.332, 0.327 and 0.257 nm. The XPS analysis results show that the binding energy of Pb 4f（7/2） in the feldspar was between 137.81-138.03 eV. Pb^2＋ can replace alkali and alkali earth cations in the feldspar structure through ion exchange reaction to form Pb-feldspar.

| Abstract: | Abstract Feldspar and Pb(NO3)2 were mixed and reacted at T=380°C to synthesize Pb‐feldspar. In the XRD (X‐ray diffraction) pattern of the product, the d values (crystal lattice spacing) of the five peaks are 0.654, 0.342, 0.332, 0.327 and 0.257 nm. The XPS analysis results show that the binding energy of Pb 4f7/2 in the feldspar was between 137.81–138.03 eV. Pb2+ can replace alkali and alkali earth cations in the feldspar structure through ion exchange reaction to form Pb‐feldspar. |
