  • Patent number: 12289806
    Abstract: A method and a device for generating light and to a use of a component for emitting light is disclosed. In a method for generating light, a component comprising a first material from the group of cuprates is subjected to an electric voltage and/or an electric field at a temperature T below 0° C. such that the component emits light. In this way, a light generation is provided which is accompanied by a substantial energy saving as well as a significantly reduced technical effort and which is also possible at cryogenic temperatures.

  • Publication number: 20230382807
    Abstract: A method for producing a densified component and an article comprising a densified component is disclosed. In a method for producing a densified component, a starting material is subjected to an electric field at a temperature (T) below 800° C. The starting material comprises a first material from the group consisting of cuprates. The method has a low technical effort, since densification is possible without heating the starting material.

  • Patent number: 11542204
    Abstract: The invention relates to a method for producing a non-oxide ceramic powder comprising a nitride, a carbide, a boride or at least one MAX phase with the general composition Mn+1AXn, where M=at least one element from the group of transition elements (Sc, Ti, V, Cr, Zr, Nb, Mo, Hf and Ta), A=at least one A group element from the group (Si, Al, Ga, Ge, As, Cd, In, Sn, Tl and Pb), X=carbon (C) and/or nitrogen (N) and/or boron (B), and n=1, 2 or 3. According to the invention, corresponding quantities of elementary starting materials or other precursors are mixed with at least one metal halide salt (NZ), compressed (pellet), and heated for synthesis with a metal halide salt (NZ). The compressed pellet is first enveloped with another metal halide salt, compressed again, arranged in a salt bath and heated therewith until the melting temperature of the salt is exceeded. Optionally, melted silicate can be added, which prevents the salt from evaporating at high temperatures.

  • Patent number: 11065686
    Abstract: A method for sintering metallic and/or non-oxide components includes completely encapsulating, in a metal halide salt, a green body comprising at least one metallic and/or non-oxide powder, and compressing the encapsulated green body so as to be gastight. The method further includes heating, together with a metal halide salt in the presence of oxygen up to sintering temperatures, the compressed, encapsulated green body. The method additionally includes at least partially dissolving, after cooling, the metal halide salt in a liquid so that the sintered component can be removed.
