Low-buIkdensity pigment particles having magnetic properties may be provided by depositing a magnetically attractable metal in the presence of low-bulkdensity silica particles from solution phase thermal decomposition of transition metal carbonyls-The pigment particles may be employed in electrostatographic magnetic development of latent images, in inks, ferro-fluids, to develop magnetic tape or film, and to form a magnetic master.
