Abstract: A core for producing a blade is formed by molding a fibrous preform around the core. The core extends in a longitudinal direction (L) between a root and a tip and has a first face and a second face connected to each other at a first longitudinal edge and at a second longitudinal edge. The core includes fluid passages formed in a transverse thickness of the core, these fluid passages being adapted to allow the passage of fluid from the first face to the second face and vice versa.

Abstract: A fluidic module includes a monolithic closed-porosity ceramic body that has a first region and a second region with the first region disposed between the second region. The first and second regions are configured to differ from one another with respect to a common attribute of a ceramic material of the ceramic body. The common attribute can differ by forming the first and second regions from ceramic particles that differ with respect their particle sizes. The fluidic module further includes a tortuous fluid passage that extends through the ceramic body. The fluid passage is surrounded by the first region such that the fluid passage is separated entirely from the second region at least within a planar region of the ceramic body. The fluid passage has an interior surface with a surface roughness of less than or equal to 5 μm Ra. A method for forming the fluidic module is disclosed.

Abstract: A component includes a component body in which at least one cavity is formed, wherein a wall surface of the component body, which wall surface delimits the cavity, is at least partially coated with a coating. The design of the component is based on a porous preform made in one or more parts from an inorganic matrix (M1), the preform having the cavity and a porous pre-coating made from an inorganic matrix (M2), the pre-coating coating at least part of a wall surface of the preform that delimits the cavity The porous preform and the porous pre-coating are infiltrated with an inorganic infiltrate (M3). The infiltrated preform forms the component body, and the infiltrated pre-coating forms the coating. A method for producing the component, wherein the preform and the pre-coating are infiltrated so as to produce the component body comprising the coating is also disclosed.

Abstract: Embodiments of the disclosure relate to a sintered ceramic article. The sintered ceramic article includes sintered ceramic particles. The sintered ceramic particles include a shell at least partially surrounding at least one core. The shell is made from a first ceramic phase, and the at least one core is made from a second ceramic phase. The first ceramic phase differs from the second ceramic phase in at least one of density, composition, or pore morphology.

Abstract: A base material utilized for supporting a separation membrane includes a plurality of coarse particles each being a ceramic particle having a particle diameter of greater than or equal to 30 μm and a plurality of fine particles each being a ceramic particle having a particle diameter of greater than or equal to 1 μm and less than 30 μm. The ratio of the number of coarse particles to the number of fine particles (i.e., coarse particle ratio) is higher than or equal to 0.05 and lower than or equal to 0.3. The coarse particles have an average aspect ratio of higher than or equal to 1.5 and lower than or equal to 2.

Abstract: A manufacturing method of a heat shield component includes a mixing step of mixing sol including a ceramic precursor with heat-expandable microspheres having an outer shell formed of thermoplastic resin and encapsulating a foaming agent so as to obtain a mixed solution, a coating step of applying the mixed solution to a substrate to obtain a coated product, and a heating step of heating the coated product to form a base body including a ceramic from the ceramic precursor, and leading the heat-expandable microspheres to foam so as to form a ceramic porous layer including closed pores in the base body. The ceramic porous layer has a porosity in a range of 40% to 70%.

Abstract: Methods for forming a unitized crucible assembly for holding a melt of silicon for forming a silicon ingot are disclosed. In some embodiments, the methods involve a porous crucible mold having a channel network with a bottom channel, an outer sidewall channel that extends from the bottom channel, and a central weir channel that extends from the bottom channel. A slip slurry may be added to the channel network and the liquid carrier of the slip slurry may be drawn into the mold. The resulting green body may be sintered to form the crucible assembly.

Abstract: A method of laser-curing and forming a honeycomb diamond grinding block made from fine-grained diamonds and a ceramic binding agent is provided. The method includes preparing a slurry, where components of the slurry, by mass ratios, include: 20-21 parts of photosensitive resin; 34.5-37 parts of aluminum-oxide powder; 4-5.5 parts of fine-grained diamond powder; 0.04-0.1 parts of a photoinitiator; a range of particle sizes of the fine-grained diamond powder is 6-8 μm; stirring the slurry to allow all components in the slurry to be fully mixed with each other to obtain a first printing material; feeding the first printing material into a light-curing printer to perform light-curing 3D printing to obtain a precursor of a finished product; and performing, by a high-temperature furnace, a degreasing operation and a high-temperature sintering treatment on the precursor to obtain the finished product of the honeycomb diamond grinding block.
