    Abstract: When a raw material graphite film bad in flatness is laminated onto another material, creases and other defects may be caused. In particular, when a graphite film having a large area is laminated, defects such as creases may be often caused. In order to solve such defects, a flatness correction treatment step is performed wherein a raw material graphite film is subjected to heat treatment up to 2000° C. or higher while a pressure is applied thereto. This flatness correction treatment gives a graphite film good in flatness. Furthermore, when the flatness of the raw material graphite film is corrected by use of a thermal expansion of a core, a graphite film small in sagging can be obtained.

    Abstract: Rapid sintering techniques for densifying zirconium dioxide based ceramic materials employing electromagnetic induction heating or inductive coupled plasma, reducing processing time from hours to minutes. In one embodiment a water-cooled coil is connected to a radio frequency power supply. The coil surrounds a susceptor body which in turn surrounds the ceramic to be sintered. The susceptor heats up in response to a magnetic field emanating from the coil as the coil receives electric power. The heat in turn is radiated from the susceptor and heats the ceramic. In another embodiment, the coil is connected to a radio frequency power supply of sufficiently high frequency and power to establish a plasma in the gas which surrounds the ceramic. The plasma then heats the ceramic. The method is especially useful for sintering ceramic dental appliances, in minutes which can lead to in situ fabrication of such appliances while a dental patient waits.

  • Patent number: 8679220
    Abstract: This invention relates to a ceramic and a cermet each having a second phase for improving toughness via phase separation from a complete solid-solution phase and to a method of preparing them. The ceramic and the cermet may have the second phase phase-separated from the complete solid-solution phase, thereby easily achieving a great improvement in toughness and exhibiting other good properties including high strength, consequently enabling the manufacture of high-strength and high-toughness cutting tools, instead of conventional WC—Co hard materials.

    Abstract: A lanthanum boride sintered body 10 includes a phase 16 including lanthanum and silicon at grain boundaries 14 between crystal grains 12 of lanthanum boride. In this lanthanum boride sintered body 10, the phase 16 exists in various configurations such as a phase 16a present at a triple point of grain boundary 14, and a phase 16b present along the grain boundary 14. This phase 16 is based on a lanthanum silicide (represented by the composition formula LaSix (0<x?2)). The lanthanum boride sintered body 10 is fabricated through a sintering step of sintering a lanthanum boride green compact by press-free sintering in an inert atmosphere or under vacuum in the presence of a silicon-containing material around and/or within the green compact. The lanthanum boride sintered body 10 having this structure exhibits a relative density of not less than 92%, and more preferably not less than 94%.

  • Publication number: 20140037390
    Abstract: A method for manufacturing a cutting insert green body from a sinterable powder, a tool set for manufacturing the cutting insert green body by that method and the green body manufactured by the tool set. The tool set has axially moving upper and lower punches and radially moving side punches. The side punches move slidably on die rods. The side punches and die rods move in channels in a base body on which a cover plate is mounted. The upper and lower punches move in through holes in the cover plate and base body, respectively. The die rods are stationary during compaction of the sinterable powder. The upper, lower and side punches form surfaces of the green body and the die rods form some of the edges of the green body. The green body can have undercuts and the edges formed by the die rods can be non-linear in shape.

  • Patent number: 8636945
    Abstract: A method for producing crystalline particles including a mixing step of producing a mixed material containing a lead-containing material and an additional material containing lithium and boron and a first firing step of firing the mixed material at a predetermined firing temperature to form polyhedral crystalline particles. The crystalline particles are used to produce a crystallographically oriented ceramic by preparing a template layer having uniform crystal orientation in a predetermined direction by fixing the crystalline particles on a substrate, forming a shaped body including a matrix layer arranged on the template layer, the matrix layer being composed of a mixed material that contains a lead-containing material and an additional material containing lithium and boron, and firing the shaped body.

  • Patent number: 8632723
    Abstract: Provided is a manufacturing method for preferentially-oriented oxide ceramics having a high degree of crystal orientation. The manufacturing method includes: obtaining slurry containing an oxide crystal B having magnetic anisotropy; applying a magnetic field to the oxide crystal B, and obtaining a compact of the oxide crystal B; and subjecting the compact to oxidation treatment to obtain preferentially-oriented oxide ceramics including a compact of an oxide crystal C having a crystal system that is different from a crystal system of one of a part and a whole of the oxide crystal B. By (1) reacting raw materials, (2) reducing the oxide crystal A, or (3) keeping the oxide crystal A at high temperature and quenching the oxide crystal A, the oxide crystal B is obtained to be used in the slurry.

  • Publication number: 20130251900
    Abstract: Refractory metal and refractory metal carbide nanoparticle mixtures and methods for making the same are provided. The nanoparticle mixtures can be painted onto a surface to be coated and heated at low temperatures to form a gas-tight coating. The low temperature formation of refractory metal and refractory metal carbide coatings allows these coatings to be provided on surfaces that would otherwise be uncoatable or very difficult to coat, whether because they are carbon-based materials (e.g., graphite, carbon/carbon composites) or temperature sensitive materials (e.g., materials that would melt, oxidize, or otherwise not withstand temperatures above 800° C.), or because the high aspect ratio of the surface would prevent other coating methods from being effective (e.g., the inner surfaces of tubes and nozzles). The nanoparticle mixtures can also be disposed in a mold and sintered to form fully dense components.
