Metal microspheres, filamented hollow metal microspheres and articles produced therefrom

Hollow film forming metal material microspheres having a diameter of 500 to 6,000 microns and a wall thickness of 0.5 to 400 microns, wherein said microspheres are free of latent solid or liquid blowing gas materials or latent blowing gases and the walls of said microspheres are substantially free of holes, relatively thinned wall portions or sections and bubbles.

Hollow film forming metal material oblate spheroids obtained by partially flattening microspheres which microspheres have a diameter of 500 to 6,000 microns and a wall thickness of 0.5 to 400 microns, said microspheres are free of latent solid or liquid blowing gas materials or latent blowing gases and the walls of said microspheres are substantially free of holes, relatively thinned wall portions or sections and bubbles.

Filamented, hollow film forming metal material microspheres having a diameter of 200 to 10,000 microns and a wall thickness of 0.1 to 1000 microns, wherein said microspheres are connected to each other by filament portions which are continuous with the microspheres and are of the same film forming metal material from which the microspheres are made.
