Modification of the surface of glass microspheres by a complex of poly-N-vinylpyrrolidone with cobalt particles

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