  • Patent number: 6081574
    Abstract: A pyrolytic carbon coated nuclear fuel particle and method of making it. The fuel particle has a core composed of a refractory compound of an actinide metal. The pyrolytic carbon coating surrounds the core so as to provide a void volume therebetween. The coating has an initial density of no greater than 1.45 grams/cm.sup.3 and an anisotropy factor than 3.0 and a final density upon heat treatment above about 2000.degree. C. of greater than 1.7 grams/cm.sup.3 and an anisotropy factor greater than 5.

  • Patent number: 4961757
    Abstract: Cutting tools are disclosed which are comprised of composite bodies comprising a ceramic matrix reinforced by ceramic whiskers. The ceramic matrix may be alumina or silicon nitride, and may contain toughening components. The whiskers are preferably silicon carbide, but may be other known ceramic whiskers. Whisker content in the composite is 2-40%, with higher contents generally used for tools when the expected service involves interrupted cutting and lower contents generally used for continuous cutting tools.

  • Patent number: 4637924
    Abstract: The invention features methods and apparatus for obtaining silicon carbide whiskers on a continuous basis. Rice hulls or other carbon and silicon containing feed materials are continuously fed to a conversion zone in an unagitated state in order to promote whisker growth. The conversion zone is continuously purged, preferably with an inert gas such as nitrogen. The purging gas is vented directly out of the conversion zone and carries away gaseous reaction products and impurities, prevents oxidation of the whiskers and keeps glasses from condensing and depositing on the furnace surfaces. The feed materials are fed in a dry state to the conversion zone in order to prevent erosion of the furnace walls. After conversion and cooling the whiskers are separated from the mass of particulate silicon carbide. The whiskers find use as reinforcements.

  • Patent number: 4077838
    Abstract: An improved nuclear fuel kernel having at least one pyrolytic carbon coating and a silicon carbon layer is provided in which extensive interaction of fission product lanthanides with the silicon carbon layer is avoided by providing sufficient UO.sub.2 to maintain the lanthanides as oxides during in-reactor use of said fuel.

  • Patent number: 4016304
    Abstract: A method for coating small diameter, low density particles with pyrolytic carbon is provided by fluidizing a bed of particles wherein at least 50 per cent of the particles have a density and diameter of at least two times the remainder of the particles and thereafter recovering the small diameter and coated particles.

  • Patent number: 4010287
    Abstract: An improved process for producing porous spheroidal particles consisting of a metal carbide phase dispersed within a carbon matrix is described. According to the invention metal-loaded ion-exchange resin microspheres which have been carbonized are coated with a buffer carbon layer prior to conversion of the oxide to carbide in order to maintain porosity and avoid other adverse sintering effects.

  • Patent number: 3944638
    Abstract: An improved method for treating metal-loaded resin microspheres is described which comprises heating a metal-loaded resin charge in an inert atmosphere at a pre-carbide-forming temperature under such conditions as to produce a microsphere composition having sufficient carbon as to create a substantially continuous carbon matrix and a metal-carbide or an oxide-carbide mixture as a dispersed phase(s) during carbide-forming conditions, and then heating the thus treated charge to a carbide-forming temperature.
