Claims19
A method of manufacturing a lead-free, non-toxic radiation shielding device, said method comprising:
- combining a liquid thermosetting polymer, at least one heavy particulate filler, and at least one light particulate filler to form a lead-free, non-toxic composite material,
- wherein said at least one heavy particulate filler is selected from a group consisting of tungsten, osmium, iridium, platinum, gold, molybdenum, tantalum, and combinations thereof, said at least one heavy particulate filler having an average particle size between 0.1 micron and 15 microns, and further wherein said at least one light particulate filler is selected from the group consisting of barium sulfate, bismuth, iodine, zirconium, zirconium oxide, nickel, copper, silver, titanium, titanium oxide, zinc oxide, zinc sulfide, antimony oxide, aluminum, and combinations thereof, said at least one light particulate filler having an average particle size between 0.5 micron and 15 microns;
- and
- casting said lead-free, non-toxic composite material to form a lead-free, non-toxic radiation shielding device.
A method of manufacturing a lead-free, non-toxic radiation shielding device, said method comprising:
- combining a solid thermosetting polymer, at least one heavy particulate filler, and at least one light particulate filler to form a lead-free, non-toxic composite material, wherein said at least one heavy particulate filler is selected from a group consisting of tungsten, osmium, iridium, platinum, gold, molybdenum, tantalum, and combinations thereof, the at least one heavy particular filler having an average particle size between 0.1 micron and 15 microns, and further wherein said at least one light particulate filler is 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 microns;
- and
- liquid phase sintering said lead-free, non-toxic composite material to form a lead-free, non-toxic radiation shielding device.
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 osmium, iridium, platinum, gold, tantalum, and combinations thereof;
- 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.
A lead-free, non-toxic composite material, said composite material comprising:
