A strong lightweight composition containing inorganic coated microparticles which, when dispersed in a binder, produce a matrix having broad band absorption properties for electromagnetic radiation in the infrared and microwave regions and is useful as a thin coating or as a structural composite material in various applications for multispectral absorbers. The microparticles have a mean diameter of from 1 to 500 microns and are coated with the reaction product of a metal and a nonmetal.

A strong lightweight composition containing metal coated microspheres has very broad band absorption properties for electromagnetic radiation and is useful as a thin coating or as a structural composite material in various applications. The microspheres have a diameter of from 1 to 350 microns and contain at least one radiation absorbing material selected from the group consisting of carbon, ferrites, magnetite, iron, nickel and cobalt, and have a thin-coating of metal on the microsphere surface. The metal coating is present at a weight percentage of 0.01 percent to 22 percent.

Electrically conductive microparticles characterized by high conductivity and low density are comprised of electrically nonconductive magnetic microballoons having an electrically conductive coating of a metal. When dispersed in an electrically nonconductive matrix, an electrically conductive composite material is formed in which the microparticles form a network of contacting particles throughout the matrix.
