摘要:
A superconductive thin layer of an oxidic material is manufactured by contacting at least two starting substances with each other, after which diffusion and a chemical reaction in the solid state occur by means of increasing the temperature, while forming the superconductive thin layer.
摘要:
A method of manufacturing a wire of superconducting oxidic material, in which a preform is used, which comprises dispersions of a superconducting material and of a non-superconducting material in a binder or which comprises dispersions of non-superconducting materials in a binder, in which latter case the materials can react whilst forming a superconducting compound, in which the preform is extruded to a wire, the binder is baked out and the wire is sintered.
摘要:
A fine-granular superconductive material, in particular YBa₂Cu₃O₇₋₆, is obtained by spray-drying an aqueous nitrate solution of the desired metal ions and subjecting the resulting powder to an oxidic treatment at high temperature. A very homogeneous bulky superconductive material can be manufactured with the resulting powder.
