Characterization of hematite sols: correlation of size, shape and percentage yield

α-Fe2O3 sols were prepared by forced hydrolysis method. The effect of time of aging, concentrations of ferric chloride and hydrochloric acid on the size, shape and percent yield were studied. Static light scattering was employed to determine the spherical shape, further confirmed by cryo-SEM techniq...

More Information
Summary:α-Fe2O3 sols were prepared by forced hydrolysis method. The effect of time of aging, concentrations of ferric chloride and hydrochloric acid on the size, shape and percent yield were studied. Static light scattering was employed to determine the spherical shape, further confirmed by cryo-SEM technique.
