1. A lead-free, non-toxic composite material, said composite material comprising:
- a thermosetting polymer;
at least one heavy particulate filler selected from a group consisting of tungsten, osmium, iridium, platinum, gold, molybdenum, tantalum, and combinations thereof, the at least one heavy particulate filler having an average particle size between 0.1 micron and 15 microns; and
at least one light particulate filler selected from the group consisting of barium sulfate, bismuth, iodine, zirconium oxide, nickel, copper, silver, titanium, titanium oxide, zinc oxide, zinc sulfide, antimony oxide, aluminum, and combinations thereof, the at least one light particulate filler having an average particle size between 0.5 micron and 15 micronswherein the light particulate filler inhibits settling of the heavy particulate filler in the composite material, and further wherein the composite material comprises a viscosity capable of casting or liquid phase sintering.
