    Abstract: The present invention relates to a method for producing an electrode material for a battery electrode, in particular for a lithium-ion battery, wherein said electrode material comprises nanostructured silicon carbide, comprising the steps of: a) providing a mixture including a silicon source, a carbon source and a dopant, wherein at least the silicon source and the carbon source are present in common in particles of a solid granulate; b) treating the mixture provided in step a) at a temperature in the range from ≥1400° C. to ≤2000° C., in particular in a range from ≥1650° C. to ≤1850° C., wherein step b) is carried out in a reactor that has a depositing surface the temperature of which relative to at least one other inner reactor surface is reduced. In summary, a method described above enables to combine a simple and cost-efficient production with a high cycle stability.

    Abstract: The present invention relates to a method for producing a fibre-reinforced, transparent composite material (10), comprising the following steps: a) providing a material matrix melt and b) producing reinforcing fibres (14), step b) of the method comprising the steps of b1) providing a mixture having a silicon source and a carbon source, the silicon source and the carbon source being present together in particles of a granulated solid; b2) treating the mixture provided in step a) of the method at a temperature in a range from ≧1400° C. to ≦2000° C., more particularly in a range from ≧1650° C. to ≦1850° C.; thereby producing reinforcing fibres (14), the method comprising the further steps of c) introducing the reinforcing fibres (14) into the material melt; and d) optionally cooling the material melt to form a transparent composite material (10). A method of this kind allows a composite material to be produced that is able to unite high transparency with outstanding reinforcing qualities.

    Abstract: The present invention relates to a process for producing a silicon carbide-containing body (100), characterized in that the process has the following process steps: a) providing a mixture (16) comprising a silicon source and a carbon source, the silicon source and the carbon source being present together in particles of a solid granular material; b) arranging a layer of the mixture (16) provided in process step a) on a carrier (12), the layer of the mixture (16) having a predefined thickness; and c) treating the mixture (16) arranged in process step b) over a locally limited area with a temperature within a range from ≥1400° C. to ≤2000° C. according to a predetermined three-dimensional pattern, the predetermined three-dimensional pattern being selected on the basis of the three-dimensional configuration of the body (100) to be produced. Such a process allows simple and inexpensive production even of complex structures from silicon carbide.
