Pigment materials having low-bulk densities are obtained by depositing a magnetic or magnetically attractable metal in the presence of and onto low-bulk density silica particles. The low-bulk density, magnetic, composite pigment particles are prepared by the solution phase thermal decomposition of transition metal carbonyls
