摘要： The present invention relates to methods and apparatus for producing tubular articles of silicon carbide and silicon. The articles contain silicon in both metallic and in chemically combined form. The method consists of the steps of concentrically positioning a vertical tubular columns of particulate silicon contiguous to a hollow, vertical tubular columns of particulate silicon carbide, carbon, or mixtures of silicon and carbon, and heating the adjacent columns to a siliciding temperature. The silicon component infiltrates the column containing the particulate silicon carbide, carbon, or mixtures thereof, forming a tubular product. The apparatus consists of supply hoppers for holding the particulate feed material, a loading means comprised of spaced, concentrically arranged, tubular forms. The loading means is positioned within a vertically positioned electrical induction furnace. Particulate feed materials are dry cast in the spaces between and around the forms. The loading means is then removed leaving separate vertical, hollow columns of particulate feed materials concentrically arranged with the furnace. The furnace is then heated from top to bottom to a siliciding temperature. The silicon component infiltrates the column containing silicon carbide, carbon or mixtures thereof to form a dense, tubular silicon-silicon carbide product.

摘要： Non-oxide refractory foams, possessing controlled permeability and uniformity, are prepared by impregnating an organic polymer foam material with a fluid, particulate slurry of a first refractory material, drying, applying to the dried, impregnated material a second refractory material which has a lower melting point than the first refractory material and thereafter heating, at a temperature sufficient to cause melt infiltration of the second refractory material into the impregnated material, thus producing inert and dimensionally stable composite refractory foams having broad utility as particulate filters or carriers.

摘要： Dense, strong, composite materials are produced from mixtures of silicon and silicon carbide. The composite materials are characterized by a mixture of finely-divided silicon carbide in a substantially continuous matrix of silicon. The composite materials contain from about 40 to about 60 percent by volume silicon carbide and from about 60 to about 40 percent by volume silicon. The composite materials are produced by initially producing a finely-divided silicon carbide starting component and forming the component into a green body of the desired shape. The green body is subsequently impregnated with molten silicon in the absence of any substantial amount of carbon. Suitably, a thermoplastic resin binder may be added to the silicon carbide starting material to aid in forming the green body. The impregnation step may be carried out by surrounding the green body with finely-divided silicon metal and heating the covered body to a temperature above the melting point of silicon. The composite materials described have flexural strength of over about 90,000 psi at 1100.degree. C., elastic modulus of about 38 million psi at room temperature, are essentially non-porus and have densities ranging from about 2.6 to about 2.8 g/cc.

摘要： The present invention relates to composite articles of manufacture comprised of a continuous phase of silicon containing a discontinuous matrix of particulate material selected from silicon carbide, carbon, or mixtures thereof. The particulate materials have a minimum size of about fifty microns, and more preferably for enhanced performance, a minimum size of 100 microns. The present articles contain from about thirty to about seventy, and more preferably from about 35 to about 65 percent by volume of silicon. The present composites have strains to failure at high temperatures substantially higher than the reaction bonded silicon carbide composites of the prior art. The present composites also have a resistance to thermal stress at elevated temperatures superior to the prior art composites. In such respects, the present composite materials have characteristics more resembling a metal than a ceramic. The present composites are especially useful in the fabrication of shaped articles, for example, tubular articles.
