Silica particles encapsulated with corrosion inhibitor sodium tungstate was synthesized through re- verse emulsion polymerization. In the emulsion polymerization system, eyelohexane was used as dispersion me- dium, Span80 and OP-10 was used as emulsifier, TEOS was used as monomer, ammonia was used as catalyst. The polydispersity of the particle's diameter was characterized with dynamic light scattering, and scanning elec tron microscopy (SEM). The distribution of the corrosion inhibitor sodium tungstate was investigated through scanning electron microscopy-X ray energy diffraction spectroscopy (SEM-EDS) and scanning transmission elec- tron microseope-X ray energy dispersive spectrometer (STEM-EDS). The results indicated that the average di ameter of the silica is about 600nm, and the corrosion inhibitor was encapsulated in the silica.
