    摘要： A ceramic welding process for forming a coherent refractory mass on a surface of a refractory which is hot and which is comprised of at least one silicon compound includes providing a mixture composed of combustible particles including silicon particles, refractory particles which are silicon carbide particles and which constitute a major portion by weight of the mixture, and particles of one of (a) another substance selected from the group consisting of CaO, MgO, FeO, and mixtures thereof or (b) particles of a nonmetallic precursor of the another substance, which another substance causes incorporation of silica, formed by combustion of the silicon particles, into a crystalline lattice of a compound formed between the silica and the another substance within the coherent refractory mass being formed; and projecting the mixture against the surface of the refractory, simultaneously with substantially pure oxygen, so that the combustible particles react in an exothermic manner by combusting with the projected oxygen and release sufficient heat to form the coherent refractory mass under action of heat of combustion, and so that silica, formed by combustion of the silicon particles, is incorporated into the crystalline lattice of a compound formed between the silica and the another substance.

    摘要： A process for producing a crystalline siliceous refractory mass includes providing particulate constituents to be projected comprised of (1) solid refractory particles comprising silica in the form of vitreous silica, and (2) solid combustible particles comprising silicon particles; projecting the particulate constituents with gaseous oxygen against a surface under ceramic welding conditions effective to cause a reaction between the solid combustible particles and the gaseous oxygen to occur against the surface, thereby releasing the heat of reaction against the surface so that a coherent refractory mass comprising cristobalite is formed, wherein the surface against which the solid refractory particles are projected is at a temperature of at least 1000.degree. C. The process can be used to manufacture refractory bricks or blocks, to repair furnaces, or to repair worn surfaces of a siliceous refractory material.

    摘要： Industrial applications of composites often require that the final product have a complex shape. In this invention intermetallic or ceramic phases are formed from sheets of unreacted elemental metals. The process described in this invention allows the final product shape be formed prior to the formation of the composite. This saves energy and allows formation of shaped articles of metal-intermetallic composites composed of brittle materials that cannot be deformed without breaking.

    摘要： In ceramic welding processes, oxidising gas and a mixture of refractory and fuel powders are projected against a surface and the fuel is burnt to generate sufficient heat that the refractory powder becomes at least partially melted or softened and a cohesive refractory mass is progressively built up against that surface. In order to reduce any tendency for the weld mass to include a low-grade refractory phase and thus promote the refractoriness of that weld mass, the fuel powder is present in a proportion of not more than 15% by weight of the total mixture and includes at least two metals selected from aluminium, magnesium, chromium and zirconium, and in that at least the major part by weight of the refractory powder consists of one or more of magnesia, alumina and chromic oxide, and in that the molar proportions of silica and calcium oxide present in the refractory powder (if any) satisfy the following expression: molar concentration of SiO.sub.2 in % .ltoreq.0.2+molar concentration of CaO in %

    摘要： An exothermic composition comprises a particulate readily oxidizable metal such as aluminum, magnesium or silicon and an organic fluorine-containing compound, and usually an oxidizing agent for the readily oxidizable metal. The preferred organic fluorine-containing compound is polytetrafluoroethylene. The composition may also contain a binder, a particulate refractory material, refractory fibres and/or organic fibres. The composition may be used in the casting of molten metal, either in particulate form or as a preformed shape such as a sleeve or board, to cover or surround molten metal in the feeder of a casting mould or in the head or head box of an ingot mould.
