    摘要： The present invention pertains to a process for producing unmeltable polysilane-polycarbosilane copolymers which are soluble in inert solvents, comprising the steps providing the product of a disproportionation of a methylchlorodisilane or a mixture of several methylchlorodisilanes of the composition Si2MenCl6-n, wherein n=1-4, wherein the disproportionation was carried out with a Lewis base as a catalyst, wherein this product is a chlorine-containing, crude polysilane/oligosilane containing hydrocarbon groups, and thermally postcrosslinking the crude polysilane/oligosilane to a polysilane-polycarbosilane copolymer, characterized in that the chlorine content of the polysilane-polycarbosilane copolymer is lowered by reacting the crude polysilane/oligosilane with a substitution agent, by which chlorine bound therein is replaced with a chlorine-free substituent. Green fibers and low-oxygen/oxygen-free ceramic fibers with a very low chlorine content can be produced using this process.

    摘要： In a method of preparing a boron carbide material, boron carbide powder is washed with essentially pure water at an elevated temperature to generate washed boron carbide powder. The washed boron carbide powder is combined with a sintering aid. The mixture of the boron carbide powder and the sintering aid is pressed to form a shaped material, and the shaped material is sintered. A sintered boron carbide material comprises a boron carbide component that includes boron carbide, elemental carbon, and not more than about 0.6 wt % of oxygen on the basis of the total weight of the boron carbide component. The sintered boron carbide material has a density of at least about 99% of the theoretical density. Another sintered boron carbide material comprises a boron carbide component that includes boron carbide, silicon carbide, elemental carbon, and not more than about 0.3 wt % oxygen on the basis of the total weight of the boron carbide component, and has a density of at least about 97% of the theoretical density.
