Abstract: Silicone fibers are produced by dry or wet spinning a solution obtained by hydrolysis of an organoalkoxysilane and/or an organoalkoxypolysiloxane, which solution also contains about 0.01 to 2% of highly polymerized poly-lower alkylene oxide, by incorporating therein a tetraalkoxysilane and/or an alkoxypolysiloxane to the extent of about 5 to 99 mole % of the silanes plus siloxanes. The spinning solution may be formed directly from reaction of the corresponding chlorosilanes with lower alkanols, removal of by-product HCl, and addition of polylower alkylene oxide and of water in up to about six times the stoichiometric amount required for complete hydrolysis of all the alkoxy groups of the silanes and siloxanes. If desired, up to 40% of a lower alkanol can be added to the solution as a solubilizing agent. The resulting novel silicone fibers can be converted to quartz fibers by heating above 600*C, and if heating is effected rapidly and/or under an inert gas varying amounts of carbon in finely disperse form will be distributed through the fiber.

Abstract: In the production of porous shaped structures suitable for carbonization by foaming an organic material capable of being carbonized, and thereafter consolidating the foamed structure as a preliminary to subsequent carbonization, the improvement which comprises employing as the organic material to be foamed and capable of being carbonized an aqueous solution of lignin. The lignin solution preferably contains about 0.01 to 5% by weight of polyethylene oxide or an acrylic acid-acrylamide copolymer having a degree of polymerization in excess of about 2,000. After foaming to achieve a density of less than about 1 gram per cubic centimeter, the foam is consolidated by heat treatment and/or acidification. The resulting product can be carbonized to form porous carbon foams.

Abstract: A melt or solution of a silazane is formed into a shaped article by molding or melt or dry extrusion and is thereafter heated in an inert atmosphere to about 800* to 2,000*C to decompose the silazane into a homogeneous mixture of silicon carbide and silicon nitride. The silazane is produced by reacting ammonia with a halogenosilane and, if effected in solution, after removal of by-product ammonium chloride and optionally concentrating, the solution is directly employed for shaping. The solution may be rendered spinnable by addition of small amounts of high polymers and various other additives may also be employed. Fibers produced therefrom are of satisfactory mechanical properties and are suited for use as insulation and reinforcement in laminates.
