    Abstract: The invention relates to a system and method for continuous production of ceramic non-wovens, essentially comprising a mixing device for the production of a suspension consisting of ceramic powder, aqueous aminoxide and cellulose. The suspension is produced in batches or in a continuous manner and can occur in one or several steps by adding all components or the individual components thereof. The invention also comprises a device for concentrating the solution made of ceramic powder, aqueous aminoxide and cellulose thus produced. The mixture is sheered in an intensively mixed heated state in said device and transported with the evaporation of water until a precisely defined amount of water is evaporated an a suspension of ceramic powder in a deformable solution of cellulose in aqueous aminoxide is obtained. The invention also comprises a device which is connected to the above-mentioned concentration device and which is used to process the deformable ceramic cellulose suspension to form ceramic green fibers. Said device enables ceramic green fibers to be formed and, optionally, a green fiber non-woven. A system can also be integrated, enabling the green fiber non-woven to be pyrolyzed and sintered or a non-woven made of ceramic green fibers to be pyrolyzed and sintered. The ceramic non-wovens thus obtained can be used in the chemical, power-generating, recycling and motor industry, in biotechnology and in medicine. Said non-wovens can also be used in catalyzer technology for use as catalyzers for internal combustion engines or in chemical reactors.

    Abstract: A continuous sheet (W) of alumina fiber precursor formed from a compound-containing spinning solution is continuously fed into a high-temperature heating furnace, and is heat treated while being conveyed in one direction by a plurality of conveying mechanisms (2, 3) disposed in the heating furnace. During the heat treating, the conveying mechanisms are decelerated in the conveying direction in conformity with the heat shrinkage of the continuous sheet (W), whereby the wear-out of fibers in the alumina fiber precursor is reduced to obtain a continuous alumina fiber blanket having uniform thickness and bulk density and being excellent in strength.

    Abstract: A process utilizing a supported metal catalyst, a volatile species source, and a carbon source has been developed to produce carbide nanorods with diameters of less than about 100 nm and aspect ratios of 10 to 1000. The volatile species source, carbon source, and supported metal catalyst can be used to produce carbide nanorods in single run, batch, and continuous reactors under relatively mild conditions. The method employs a simple catalytic process involving readily available starting materials.

    Abstract: The pool (11) to be filamented is liquefied by heating in a crucible (10). A disk (15) having an edge (16) immersed in the molten pool (11) rotates at high velocity and drives the pool outwards in the form of a ribbon (7) which breaks up into pieces forming the required particles. The portion of the pool in contact with the disk (15) is constantly replenished and, owing to the use of heating means (30), has sufficient fluidity to satisfy the conditions for extraction, the molten pool (11) being continuously moved horizontally with respect to the disk (15).
