✦ Synopsis

Submicron spherical particles of colloidal silica were prepared by the hydrolysis of sodium silicate in a Triton X-100-hexanot-cyclohexane-water microemulsion system . The average diameter of the silica particles obtained was about 30 not The formation of a microemulsion by using a cyclohexane solution of Triton X-100 was described . The effects of temperature and the concentration of the aqueous Na 2 SiO, solution on the solubilization were investigated and the results showed that the solubilization decreased with increasing concentration of Na 2 SiO, and that an optimum temperature existed for the system .

Nanoparticles of tin oxide (SnO 2 ) have been prepared from water-in-oil microemulsions consisting of water, AOT (surfactant), and n-heptane (oil). Precursor hydroxides were precipitated in the aqueous cores of water-in-oil microemulsions and then calcined at 600°C for 2 h to form tin oxide powder.
