ABSTRACT:
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.
