摘　　要：采用水 (溶液 ) /Triton X-1 0 0 /环己烷 /正戊醇微乳体系 ,制备片状 Pb SO4 纳米晶 ,并利用 TEM对产物进行了表征 .考察并初步讨论了微乳体系中几种因素对其尺寸及形貌的影响以及 Pb SO4Plate\|like nanocrystal PbSO\-4 was synthesized in quaternary W/O microemulsion system containing water, Triton X\|100, cyclohexane and \%n\%\|pentanol. Transmission electron microscopy(TEM) was utilized to characterize the morphology of PbSO\-4 as\|prepared and electron diffraction(ED) analysis identified the crystal nature of the product. Two key variables\%ω\%\-0(molar ratio of water to surfactant) and reactant concentration in water were investigated to reveal the formation and self\|assembly mechanism as well as the shape and size changing of plate\|like nanocrystal PbSO\-4 under different conditions.
