摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing, at a low cost and stably, a ceramic body having a large size, a large area, and a thin wall. SOLUTION: The method for manufacturing a large-sized thin-walled ceramic body comprises: a step, in which slurry of a ceramic raw material powder is poured into a die having heat resistance, dried, and solidified; and a step, in which a formed body formed in the inside or on the surface of the die is placed in a firing furnace together with the die without taking out the body from the die, heated to a prescribed temperature, sintered, and taken out from the die after cooling of the furnace. Since the ceramic body is fired as it is after forming without being taken out from the die, handling of the formed body becomes unnecessary, so that the large-sized thin-walled ceramic body is easily obtained.

The burnt surfaces have undulations formed thereon so as to have the regularity in arrangements and dimensions and so as to be integrated with a base material. Further, a method for manufacturing the member for molten metal, which member has the undulations formed thereon so as to have the regulated shape, size, arrangement, and interval, is provided. Because its contact area with the molten metal can be reduced, the member is hardly wetted by the molten metal, and is excellent in its durability, thermal shock resistance, and measurement accuracy, and is stable in its quality.

摘要： PROBLEM TO BE SOLVED: To provide a ceramic composite with an ultra-flat and smooth surface stably formed on the surface of a nonoxide-base ceramic, and a method for producing the same. SOLUTION: The ceramic composite formed of the dense and ultra-flat and smooth surface is produced by a step to mold a mixed powder comprising silicon and oxides as principal components, a step to fire the molding in a nitrogen-containing gas stream to convert the silicon into silicon nitride and simultaneously sinter the molding, and a step to heat the molding in an atmosphere containing oxygen to exude oxides present inside the sintered body to the surface by virtue of a capillary phenomenon, and a step to cool the molding to be solidified. Accordingly, the ceramic sintered body having a stable and ultra-flat and smooth surface hardly obtainable by working or blowing and the production method therefor are thus achieved.

摘要： PROBLEM TO BE SOLVED: To provide a stoke having strength, wear resistance, corrosion resistance and thermal shock resistance necessary for a cast member, and also having economical efficiency, durability and consistent quality while any slag is hardly deposited thereon.
SOLUTION: In the casting stoke with the slag deposition preventive function and its manufacturing method, the stoke is used for casting molten aluminum, and has unevenness including a large number of polygonal pyramids, spherical projections, groove and/or holes in a strip-shaped area forming a part in contact with slag floating at least in the vicinity of the level of the molten aluminum. The part having the unevenness is filled with inorganic substances as necessary. Since the inorganic substances are filled in the projections and holes on the surface, bonding with a base metal is increased, and the crack propagation in a thick film is suppressed thereby. Further, in the member for the molten aluminum with the slag deposition preventive function, the slag is hardly deposited thereon and the quality is consistent.

SOLUTION: A manufacturing method of the acicular ceramic body using an acicular cordierite whose tip part is roundish as the substrate, and a manufacturing method of the acicular ceramic catalytic body carrying the catalyst, and a manufacturing method of a ceramic body wherein a part of a raw material (fluoride) gasified by the reaction between raw materials in a burning process of the acicular ceramic body is grown into a roundish acicular shape on a metal catalyst (Fe) by a vapor phase-liquid phase-solid phase (VLS) reaction so that the tip part of the acicular particle may be the roundish acicular shape are provided. A honeycomb structure for carrying the catalyst composed of the acicular ceramic is suppressed in decrease of the specific surface area by sintering and early stage activation of the catalyst is possible since a heat capacity is small and pressure drop is low.
