Abstract: Polycrystal nanowires of orthorhombic PbCl2, with diameter of 20—30 nm, length up to tens microns, and cell constants of a=0.454 nm, b=0.763 nm, c=0,904 nm, were synthesized by micelle template of polyoxyethylene(9)-dodecyl-ether(C12E9), n-pentanol and cyclohexane when the molar ratio of water to C12E9, R, is 10, the volume ratio of cyclohexane to C12E9 is 8, c(C12E9) is 0.18 mol/Land the concentration of c(Pb 2+) and c(Cl-) are 0.1 mol/L.The middle process and an intermediate were captured. On the basis, the formation mechanism of PbCl2 nanowires were studied. The results indicated that the formation of PbCl2 nanowires was probably via the mechanism of the directional aggregation and orientated growth of the PbCl2 colloidal particles.
