ABSTRACT:
Silica microspheres formed by hydrolysis of a silica precursor having a mean diameter in the range of about 0.1 to 10 .mu.m are provided with a thin surface layer, often a monolayer, of a metal to provide the appearance of a solid particle of the metal as its oxide. The microspheres are contacted with an aqueous or alcoholic solution of a metal compound to deposit the surface layer.
