title: Silica Coating on Colloidal Maghemite Particles.
abstract: Maghemite colloidal particles are coated with a silica layer using a silicon alkoxide as silica precursor. The coating process is studied by electrophoresis, quasi-elastic light scattering, nitrogen adsorption, and infrared spectrometry analyses. The conditions of complete coverage of the iron oxide particles by silica and the nature of the maghemite-silica interface are discussed. Copyright 1999 Academic Press.
