    Abstract: A process and powder mixture are provided for the ceramic welding repair of electrocast refractory oxide materials, such as those used in parts of glassmaking and metallurgical furnaces exposed to severe high temperature conditions. The powder mixture, which is to be projected in an oxygen gas stream against a refractory surface to be repaired, comprises combustible particles such as aluminium and silicon and refractory oxide particles plus at least one constituent, for example sodium carbonate and/or excess silica, which produces a vitreous phase in the repair mass, thereby enhancing the bond between the repaired refractory material and the repair mass.

    Abstract: A method to at least partially impregnate a porous ceramic body with a metal comprising positioning a sacrificial porous ceramic transport means in physical contact with the metal and between the porous ceramic body to be impregnated and the metal; interposing a sufficient amount of a ceramic powder in contacting relationship between the ceramic body and the transport means to enable the metal to flow from the ceramic transport means to the ceramic body and insufficient to permit metal bonding between the transport means and the ceramic body, at least one constituent of the powder being wettable by, and chemically reactive with the metal; and maintaining at least the ceramic body and metal transport means at a temperature, and for a time, sufficient for at least a portion of the metal to flow through the transport means and into the ceramic body to impregnate the ceramic body a predetermined amount to form a metal impregnated ceramic body of near net shape.

    Abstract: A ceramic sinter is produced by utilizing the heat of reaction of the thermit process as the heat source, wherein a preheating step precedes a sintering step, or a mixture of: (A) at least one ceramic powder, (B) at least one nonmetallic powder selected from the group consisting of carbon, boron and silicon powders, and (C) a metal powder and/or a nonmetallic powder other than the above-mentioned powder (B), is used as the raw material. This method gives homogeneous dense ceramic sinter and composite ceramic sinter. Furthermore the fine textures of the sinter and the composition and distribution of the composite ceramic phase can appropriately be controlled thereby.

    Abstract: A dense essentially non-porous composite ceramic material of a diboride of a group IVa metal, preferably titanium, and alumina in a 3 : 5 mole ratio has a macroscopically uniform structure made up of non-uniformly dispersed agglomerates of alumina of random shapes and dimensions and a fibrous sponge-like electrically conductive structure of submicronic grains of the group IVa metal boride in intimate wetting contact with the alumina agglomerates. The material is made by reaction hot pressing of coarse grain precursor powders.
