ABSTRACT:
Spherical particles include a core of a polymer and a metal compound covering the polymer core. These particles may be formed by homogeneously dispersing particles of a polymeric compound in an aqueous solution of a hydrolyzable metal salt to form a uniform metal layer around the spherical particles. The spherical particles can also include a core of carbon and a metal compound covering the carbon core or the particles can have a hollow core prepared by heating spherical polymer particles coated with a metal compound to a temperature of 150.degree. C. or higher in the presence of oxygen to completely decompose the polymeric compound. These spherical particles are useful in electronic materials, magnetic materials and the like.
