Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
59 words
A method of manufacturing a superconductive thin layer of an oxidic material, characterized in that at least two starting substances are contacted mechanically with each other after which diffusion of the starting substances and reaction thereof while forming the superconductive thin layer are produced by means of increasing the temperature, diffusion and reaction taking place in the solid state.
Claim 2
Independent Claim
59 words
A method of manufacturing a superconductive thin layer of an oxidic material, characterized in that at least two starting substances are contacted mechanically with each other after which diffusion of the starting substances and reaction thereof while forming the superconductive thin layer are produced by means of increasing the temperature, diffusion and reaction taking place in the solid state.
Claim 3
Dependent Claim
44 words
A method as claimed in Claim 1, characterized in that one of the starting substances forms a substrate on which the other starting substance(s) is (are) provided in the form of a thin layer, after which the step for increasing the temperature takes place.
Claim 4
Dependent Claim
42 words
A method as claimed in Claim 1, characterized in that the starting substances are provided on an inert substrate in the form of two thin layers one on top of the other, after which the step for increasing the temperature takes place.
Claim 5
Dependent Claim
22 words
A method as claimed in Claim 1, characterized in that the step for increasing the temperature is carried out in oxidizing circumstances.
Claim 6
Dependent Claim
32 words
A method as claimed in Claim 2 of manufacturing a superconductive thin layer of YBa₂Cu₃O 7-δ , in which a substrate of Y₂Cu₂O₅ is used having thereon a thin layer of BaCuO₂.
Claim 7
Dependent Claim
31 words
A method as claimed in Claim 2 of manufacturing a superconductive thin layer of YBa₂Cu₃O 7-δ in which a substrate of CuO is used having thereon a thin layer of Y₂Ba₄O₇.
Claim 8
Dependent Claim
42 words
A method as claimed in Claim 2 of manufacturing a superconductive thin layer of Y₂Ba₂Cu₃O 7-δ in which a substrate of Y₂BaCuO₅ is used having thereon a thin layer of a mixture of 40 mol % CuO and 60 mol % BaCuO₂.
Claim 9
Dependent Claim
46 words
A method as claimed in Claim 3 of manufacturing a superconductive thin layer of La x Me 2-x CuO₄ in which Me is chosen from Ca, Sr and Ba, wherein x is between 1 and 2 and wherein thin layers are used of La₂CuO₄ and LaMeCuO₄.
