Hollow metal microspheres are made from film forming metal compositions and are used to make superior high strength light weight structures, improved insulating materials and insulating systems, or the microspheres can be used as filler materials in plastics, in plastic foam compositions, in rubber and rubber compositions and in metal compositions. A thin metal coating can be deposited on the inner wall surface of the microspheres. The hollow metal microspheres can also be made in the form of filamented metal microspheres in which a thin metal filament connects adjacent microspheres. The microspheres are characterized by being free of latent solid or liquid blowing gas materials or gases and the walls of the microspheres are substantially free of holes, relatively thin walled portions or sections and bubbles. Masses of the hollow microspheres and shaped forms of or containing the hollow microspheres are also described.
