摘要： Cellular ceramic materials, for example closed cell glass ceramic materials, for use in construction of buildings comprising a clay material, carbon, and water used to form the cellular ceramic blocks, slabs and beams by expansion of the particles inside the ware. The cellular ceramic materials are produced by first mixing the clay, carbon and about 40% to about 70% water by weight of the clay in the mixture, allowing the mixture to cure, drying the cured mixture, then firing the dried mixture at a temperature and for a period of time sufficient to melt the surface of the mixture. The clay material can be, for example, surface clays, ball clays, kaolin, shale, fly ash and/or bentonite. In another embodiment a mixture of volcanic ash, carbon and water can be formed and layered with the mixture of clay, carbon and water. The cellular ceramic materials are, in most cases, impervious to liquid, are capable of supporting substantial loads in tension and compression without reinforcement, and require no additional insulating material. Such cellular ceramic material may also be used in the construction of buildings with a metal skeleton comprising metal bars forming a structure for supporting the cellular ceramic building material.

摘要： Disclosed is anti-alumina-buildup refractories for casting nozzles, which comprises a refractory aggregate including 20 mass % or more of CaO component, and 10 mass % or more of clinker particles each containing CaO as a mineral phase, on the basis of 100 mass % of the entire composition. At least a part of the surfaces of the CaO exposed from the surfaces of the corresponding clinker particles is formed with a CaCO3 film. The CaCO3 film releases CO2 gas through thermal decomposition to smooth an operative surface of the nozzle so as to prevent the accretion of metal thereon, so that CaO is continuously supplied to alumina attached on the operative surface to prevent alumina buildup. In addition, the CaCO3 film effectively prevents the hydration of CaO due to a hydration reaction.
