A radial distribution of cobalt metal particles in an alumina sphere was controlled by impregnation of the spheres with a solution composed of cobalt nitrate dissolved in ethylene glycol, ethyl silicate, and a small amount of nitric acid. The radial position of cobalt narrow band in the sphere was varied with the impregnation time and the cobalt loading was controlled by the concentration of cobalt nitrate in the impregnation solution. It was also found that porous SiO<SUB>2</SUB> film resulted from the gelling of ethyl silicate covered whole external surface of the sphere.
