Full-fiber burner brick and preparation method thereof

A full-fiber burner brick and a preparation method thereof, comprising mixing alumina crystal fiber and amorphous ceramic fiber with both of them being a combination of fibers of different lengths gradations, and moreover adding fine powder fillers of different particle size gradations and supplementing other additives. This enables the internal structure of the product more uniform, increases the bulk density of the product, and also benefits the suction filterability of fiber cotton blank, and is conducive to forming and improving the strength of the blank. The surface of the brick body is further provided with a coating, which can effectively protect the cotton fiber of the brick body fiber from harsh environments, improve its high temperature resistance, and help to extend the service life of the burner brick.

METHOD FOR CLOSING AN ORIFICE OF A SILICON CARBIDE-BASED CONTAINER

A method for closing an orifice of a container. The method involves first providing a silicon carbide-based container comprising a cavity that is open by an orifice, of a silicon carbide-based plug and of a brazing material borne by the plug and/or the container. A solid object is housed in the cavity. Then the orifice is closed by brazing the plug onto the container. The brazing involves the melting the brazing material followed by solidification of the brazing material so as to form a solid joint between the container and the plug. At least a part of the cavity, referred to as a cold part, in which the solid object is housed, is kept at a temperature lower than the degradation temperature of the solid object during the brazing.

Formulations Containing Biologically Prepared Fibers

Disclosed herein are formulations comprising biologically prepared fibers and methods of preparing said formulations. These formulations can be utilized for repair of structures comprised of a variety of materials, including cementitious material, natural rock, mortar, and concrete. The formulation includes biologically prepared fibers, and a solvent or carrier solution. The formulation may additionally and optionally incorporate at least one enzyme. Once the formulation containing the biologically prepared fibers is applied to a void or crack within the structure, the fibers form a three-dimensional fibrous scaffold configuration in the void of the structure.

METHOD FOR REPAIRING CERAMIC COMPOSITE COMPONENTS

A method for repairing a component that comprises a ceramic matrix composite (CMC) material includes forming a repair insert defined by a repair geometry where the repair geometry is based on a repair area of the component, and the repair insert comprises a monolithic ceramic. Inserting the repair insert into the repair area and applying a CMC face sheet to the repair insert. The method further includes bonding the repair insert to the CMC face sheet, the repair insert to the component, and the CMC face sheet to the component. The method also includes thermally processing and densifying at least one of the repair insert or the CMC face sheet in the repair area.
