A method for producing a heat-resistant roll, and a roll produced by the method, the method including: fabricating a roll part comprising 5 wt % or more of a clay mineral; grinding the roll surface of the roll part; conducting a surface treatment in which the ground roll surface is smoothed in a moisturized state; and forming a coating film of a clay mineral on the surface-treated roll surface.

A composite material comprising 50 to 95 mass % grains of primary material selected from the group consisting of talc, mica, graphite and hexagonal boron nitride, and 0.01 to 40 mass % fibers having a length of 0.05 to 20 mm, and a ratio of length to diameter of at least 5. The grains of the primary material have a mean size of 3 to 50 microns.

Disclosed are a functional image tile and a manufacturing method therefor, the tile: being manufactured by printing a desired image on a surface of a tile manufactured through a mixture produced by mixing red clay, basalt fiber and mulberry fiber with a raw material formed by mixing plaster and water; being capable of smoothly absorbing ink during image printing since the red clay and the plaster having excellent absorbency are mixed; enabling the image printed on the surface thereof to be prevented from peeling off or spreading by moisture; and exhibiting excellent heat resistance, strength, and moisture-adjusting capability since the basalt fiber and the mulberry fiber are mixed together.

A molded three-dimensional insulator that is suitable for use in an end cone region of a pollution control device and a method of making the insulator are described. The insulator includes ceramic fibers that have a bulk shrinkage no greater than 10 weight percent. The ceramic fibers can contain alumina and silica and can be microcrystalline, crystalline, or a combination thereof.

A self-confining structural article includes a ceramic matrix with a reinforcement member disposed within the ceramic matrix. The reinforcement member is continuous, and has a mesh with holes not exceeding 4 mm in size.

Provided is a method for producing an inorganic fiber-bonded ceramic material, which can produce, at a high yield, an inorganic fiber-bonded ceramic material with fewer defects, and with an end part and a central part equivalent to each other in microstructure and mechanical properties, and also makes it possible to increase the ceramic material in size. The method for producing an inorganic fiber-bonded ceramic material is characterized in that it includes: a first pressing step of setting, in a carbon die, a laminate to be surrounded by a ceramic powder, the laminate obtained by stacking a coated inorganic fiber shaped product including an inorganic fiber part of inorganic fibers that have a pyrolysis initiation temperature of 1900 C. or lower, and a surface layer of an inorganic substance for bonding the inorganic fibers to each other, and pressing the laminate at a temperature of 1000 to 1800 C. and a pressure of 5 to 50 MPa in an inert gas atmosphere; and a second pressing step of pressing a ceramic coated laminate obtained in the first pressing step at a temperature of 1600 to 1900 C., which is higher than that in the first pressing step, and at a pressure of 5 to 100 MPa in an inert gas atmosphere.
