Abstract
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.
