  • Patent number: 6899827
    Abstract: Sintered, translucent ceramic microbeads, preferably alumina, titania, zirconia, yttria, zirconium phosphate, or yttrium aluminum garnet (YAG) are doped with one or more optically active species. The beads may be added to substances such as explosives in order to create a distinctive optical signature that identifies a manufacturer, lot number, etc. in the event of the need for forensic analysis. Because the beads have a generally spherical surface, the radius of curvature provides an additional distinguishing characteristic by which a particular sample may be identified. The beads could also be formulated into paints if needed to create distinctive optical signatures for camouflage, decoys, or other countermeasures and could also be applied as a dust to track the movement of personnel, vehicles, etc.

  • Patent number: 6821474
    Abstract: The invention allows the fabrication of small, dense beads of dielectric materials with selected compositions, which are incorporated into a polymeric matrix for use in capacitors, filters, and the like. A porous, generally spherical bead of hydrous metal oxide containing titanium or zirconium is made by a sol-gel process to form a substantially rigid bead having a generally fine crystallite size and correspondingly finely distributed internal porosity. The resulting gel bead may be washed and hydrothermally reacted with a soluble alkaline earth salt (typically Ba or Sr) at elevated temperature and pressure to convert the bead into a mixed hydrous titanium- or zirconium-alkaline earth oxide while retaining the generally spherical shape. Alternatively, the gel bead may be made by coprecipitation. This mixed oxide bead is then washed, dried and calcined to produce the desired (BaTiO3, PbTiO3, SrZrO3) structure. The sintered beads are incorporated into a selected polymer matrix.

  • Publication number: 20030162007
    Abstract: A graded composite energy converting article having a working surface of carbon-bonded carbon-fiber (CBCF) material that can absorb light, RF, microwaves, or other forms of energy and convert this energy to sensible heat. Conversely, CBCF can take sensible heat and convert it to radiative emissions of IR energy. Energy is conducted through the article by carbon foam to a secondary surface. The graded composite is made by first heating pitch under pressure to create the foam, which is then pyrolyzed and graphitized to create graphitic, open-cell foam. A slurry of chopped carbon fibers and organic binder in water or solvent is prepared and deposited on a working surface of the foam, preferably infiltrating the foam to some depth. The green body is dried, cured, and carbonized, creating a graded body of carbon foam in conductive thermal contact with a working surface of CBCF. Secondary surfaces of the foam may optionally be metal-infiltrated for added strength, brazability, or other purposes.
