Feldspar and Pb(NO 3 ) 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 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.
