This method includes dry sieving of the composition with a sieve for which the mesh diameter is less than or equal to 1,000 m, dry blending of the sieved composition, deposition of the blended composition in a mold, this mold preferably being pre-heated, molding by thermocompression of the blended composition with induction heating of the mold, and removal from the mold of the thermocompressed composition leading to the obtaining of the composite bipolar plate. A composite bipolar plate manufactured by this method, to the use of this composite bipolar plate as well as to a fuel cell including such a composite bipolar plate.

A process for forming a fluidic module (150) with integrated fluid separation includes positioning a first positive passage mold (115A) of a first fluid passage (170) having a tortuous shape within a volume of binder-coated ceramic powder (110A) and positioning a second positive passage mold (115B) of a second fluid passage (175) having a tortuous shape within the volume of ceramic powder (110A) and spaced apart from the first positive passage mold (115A). The process further includes positioning a powder interconnect (120) adjacent to a portion of each of the first (115A) and second positive passage molds (115B) within the volume of ceramic powder (110A), pressing the volume of ceramic powder (110A, HOB) with the first and second positive passage molds (115A, 115B) and the powder interconnect (120) inside to form a pressed body (148), heating the pressed body to remove the first and second positive passage molds (115A, 115B), and sintering the pressed body (148) to form a closed-porosity ceramic body (150).

A method of producing a multicolor glass-ceramic blank (10) for dental purposes. A glass-ceramic blank (10) is produced from at least a first material powder (18) and a second material powder (20), wherein the first material powder (18) and the second material powder (20) are different-colored and wherein at least one of first material powder (18) and second material powder (20) has nanoparticles (14) and/or glass-ceramic particles (16). The first material powder (18) and the second material powder (20) are introduced into a mold (22) in order to form at least one powder mixture aggregate (26). Additionally, the powder mixture aggregate (26) is compressed by hot pressing in order to form the glass-ceramic blank (10). A multicolor glass-ceramic blank (10) is obtainable by such a method and the multicolor glass-ceramic blank (10) is used as dental material.

A device and a process for forming a monolithic substantially closed-porosity ceramic fluidic device having a tortuous fluid passage extending through the device, the tortuous fluid passage having a smooth interior surface, a material of the ceramic body having a continuous and uniform distribution of grains at least between opposed major surfaces of the ceramic body. The process includes positioning a positive fluid passage mold within a volume of binder-coated ceramic powder, pressing the volume of ceramic powder with the mold inside to form a pressed body, heating the pressed body to remove the mold, and sintering the pressed body. A relationship between a first stability characteristic of the volume of ceramic powder and a second stability characteristic of the mold prevents discontinuities in the pressed body after pressing and/or during heating.

In one aspect, evaporator boats are provided which, in some embodiments, exhibit resistance to corrosion and associated performance degradation imparted by exposure to molten metals, including aluminum. An evaporator boat described herein comprises a body and an evaporator surface, the body comprising a boron nitride (BN) component and a TiB.sub.2 component including a solid solution of TiB.sub.2 and one or more elements selected from the group consisting of silicon and metallic elements of Groups IVB-VIIIB of the Periodic Table.

A method may include depositing, from a slurry, suspension, or tape, on a surface of an additively manufactured component comprising a metal or alloy, powder comprising at least one of a metal, an alloy, or a ceramic; sintering the powder to form a surface layer on the additively manufactured component; and hot isostatic pressing the additively manufactured component and the surface layer.

The present invention relates to a health artificial pearl and a manufacturing method therefor and, more specifically, to: a health artificial pearl formed by spray-drying and pressure-firing a functional mineral that emits anions and radiates far infrared rays, so as to form a core with high compressive strength, and by coating the surface of the core with an artificial pearl composition, which is nontoxic to the human body; and a manufacturing method therefor. The method for manufacturing a health artificial pearl comprises: (S100) a material pretreatment step of wet-grinding a functional mineral that emits anions and radiates far infrared rays so as to form a wet-ground solution, and spray drying the wet-ground solution so as to prepare a powder for press forming; (S200) a press forming step of injecting, into a press forming apparatus, the powder for press forming so as to form a core, and high-temperature-firing the core; (S300) a core polishing step of polishing the high-temperature-fired core; and (S400) a coating step of coating the polished core with an artificial pearl composition.

A ceramic lithium indium diselenide or like radiation detector device formed as a pressed material that exhibits scintillation properties substantially identical to a corresponding single crystal growth radiation detector device, exhibiting the intrinsic property of the chemical compound, with an acceptable decrease in light output, but at a markedly lower cost due to the time savings associated with pressing versus single crystal growth.

A method for making a ceramic heat sink is provided. In the first step of the method, a mixed material of nitrite-based ceramic powder, titanium powder and inorganic resin is prepared. The mixed material is then molded into a ceramic blank with a mold coated with titanium. Thereafter, the ceramic blank may be sintered to form the ceramic heat sink. Since the mixture and the mold both contain a common material of titanium, the molded ceramic blank can be easily removed from the mold in its integrity.
