摘要: A method for producing microencapsulated fuel pebble fuel more rapidly and with a matrix that engenders added safety attributes. The method includes coating fuel particles with ceramic powder; placing the coated fuel particles in a first die; applying a first current and a first pressure to the first die so as to form a fuel pebble by direct current sintering. The method may further include removing the fuel pebble from the first die and placing the fuel pebble within a bed of non-fueled matrix ceramic in a second die; and applying a second current and a second pressure to the second die so as to form a composite fuel pebble.

摘要: A high-flux silicon carbide ceramic filter membrane and a preparation method thereof are provided. In the preparation method, a separation layer is directly coated at a time on the basis of a support, that is, after the support is sintered, the separation layer is directly coated and then sintered for carbon removal. In the present disclosure, a sintering process and a coating formula are optimized to prevent fine silicon carbide particles from entering micropores of a support due to capillary filtration and film formation during coating, such that a separation layer with an average pore size of 0.2 μm or less can be directly coated on a silicon carbide support with an average pore size of 10 μm or more, and fine silicon carbide particles can be effectively prevented from entering micropores of the support during the coating.

摘要: Provided herein are rapid, high quality film sintering processes that include high-throughput continuous sintering of lithium-lanthanum zirconium oxide (lithium-stuffed garnet). The instant disclosure sets forth equipment and processes for making high quality, rapidly-processed ceramic electrolyte films. These processes include high-throughput continuous sintering of lithium-lanthanum zirconium oxide for use as electrolyte films. In certain processes, the film is not in contact with any surface as it sinters (i.e., during the sintering phase).

摘要: The present invention provides a method for making a high strength, small grain size ceramic having a transgranular fracture mode by rapid densification of a green body and subsequent cooling of the densified ceramic. The ceramic may include dislocations, defects, dopants, and/or secondary phases that are formed as a result of the process and resulting in stress fields capable of redirecting or arresting cracks within the material. This ceramic can maintain transparency from ultraviolet to mid-wave infrared.

摘要: The present application discloses and claims a method to make a flexible ceramic fibers (Flexiramics™) and polymer composites. The resulting composite has an improved mechanical strength (tensile) when compared with the Flexiramics™ respective the nanofibers alone. Additionally a composite has better properties than the polymer alone such as lower fire retardancy, higher thermal conductivity and lower thermal expansion. Several different polymers can be used, both thermosets and thermoplastics. Flexiramics™ has unique physical characteristic and the composite materials can be used for numerous industrial and laboratory applications.

摘要: A ceramic gas injector and method of fabrication are described. The gas injector has an inlet portion to which a gas is introduced via an inlet hole and contains a conformal channel between the inlet hole and a sidewall, an outlet portion from which the gas is provided from the gas injector and a collar disposed between the inlet and outlet portions. The channel extends into the collar. The channel has channel sections each of which extends through the inlet portion and terminates at both inlet ends before reaching the inlet face and collar ends before reaching the outlet portion. Alternating adjacent pairs of channel sections are connected via the inlet ends with adjacent pairs that are not connected via the inlet ends connected via the collar ends. Ports in a sidewall of the collar are connected with an adjacent pairs of sections not connected via the inlet ends.

摘要: The invention relates to a polycrystalline IR transparent material produced by sintering chalcogenide powder, e.g., ZnS powder, using hot uniaxial pressing followed by hot isostatic pressing. The microstructure of the material described in this disclosure is much finer than that found in material produced using the state of the art process. By using a powder with a particle size fine enough to improve sintering behavior but coarse enough to prevent a lowering of the wurtzite-sphalerite transition temperature, a highly transparent material with improved strength is created without degrading the optical properties. A high degree of transparency is achieved during hot pressing by applying pressure after the part has reached a desired temperature. This allows some degree of plastic deformation and prevents rapid grain growth which can entrap porosity. The crystallographic twins created during this process further inhibit grain growth during hot isostatic pressing.
