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 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.
