n this study, well-dispersed silica nanoparticles with a
diameter reach less than 1 nmwere prepared via amodified
sol-gel method. The modulation of particles size was utilized
through directing strong magnetic fields (0.5- 3T), on the
silica sol, during the polycondensation process. Through
controlling the preparation conditions; pH, magnetic field
strength and exposure time, the silica nanoparticles size,
which suspend in the sol, were decreased or increased
accordingly.
Effects of magnetic field on the particle size and particle
size distribution of silica sols were examined by means of
dynamic light scattering. XRD spectra showed crystalline
features for some silica sol coated films that were dried at
room temperature.
