Abstract
The effect of poly-N-vinylpyrrolidone on the size characteristics, morphology, composition of particles obtained by the reduction of cobalt ions in aqueous solutions, and the distribution of particles over the surface of glass microspheres has been studied. The reduction of cobalt ions in the absence of poly-N-vinylpyrrolidone leads to the formation of particles with a size of 200 nm on the surface of glass microspheres. The use of poly-N-vinylpyrrolidone made it possible to obtain particles ranging in size from 30 to 300 nm, with a more localized distribution of particles on the surface of glass microspheres. The resulting particles are a mixture of metallic cobalt and cobalt oxides.
