Glass microsphere/cobalt composites were successfully prepared by an electroless plating method in alkaline solution. The as-obtained samples were characterized by XRD, SEM, and VSM techniques. It was found that the concentrations of cobalt salt and aqueous ammonia greatly influenced the microstructure of cobalt coatings. A compact, uniform and continuous cobalt coating could be deposited on the surface of the glass microspheres by adjusting the synthetic parameters. The cobalt layer possessed hexagonal-close-packed phase structure. The magnetic measurement demonstrated that the glass microsphere/ cobalt composites exhibited ferromagnetic nature with saturation magnetization of 21.1 emu/g and coercivity of 382.9 Oe, respectively. Compared to the cobalt bulk, the composites showed a decreased saturation magnetization value but an enhanced coercivity.
