TL;DR: In this paper, a unique porous ceramic with complex pore structure was synthesized by the freeze-dry process, where a water-based ceramic slurry was frozen while controlling the growth direction of ice, and sublimation of the ice were generated by drying it at a reduced pressure.

TL;DR: In this paper, a method of manufacturing fiber composite ceramic is presented, in which large number of BN-coated SiC fibers are gathered to form yarns, or yarns are woven to form a two-dimensional or three-dimensional fabric, and a preform is formed by the yarns or the fabric, a molten Si is impregnated into the compact to form an SiC matrix between fibers.

TL;DR: In this paper, a SiC-whisker-reinforced Si3N4 was fabricated by extrusion and hot-pressing and a unidirectional alignment of the whiskers was achieved through sheet forming.

TL;DR: In this paper, the carbon fibers of this invention were characterized in that irreducible inorganic material particles in a mean primary particle size below 500 nm and reducible inorganic materials particles in an arbitrary size below 1 μm were mixed by pulverizing and then, the mixture was heat treated under the reducing atmosphere and metal particles were obtained, and the mixed powder of the thus obtained metal particles with the IRQM particles were included in the carbon fiber.

TL;DR: In this paper, the dispersion particles are composed of a composite oxide including at least one kind of a first metallic element selected from alkaline earth metals such as Mg and Ca, and at least a second metallic element from W, Ti, Ta, Mo, Nb, V, B, Te, Ge and Si.
