Abstract
A method for manufacturing a pipe from a superconducting ceramic material is disclosed, which comprises providing a hollow supporting metallic body having a hollow inside section therein, introducing into the hollow inside section of the hollow supporting body a liquid into which is mixed a superconducting ceramic powder material comprising an oxidized copper material, drying the above liquid, so that the superconducting ceramic material is coated on the inside of the supporting body with a hollow space kept therein; and firing the supporting body and the ceramic material in an oxidizing atmosphere.
Claims3
A method for manufacturing a pipe from a superconducting ceramic material comprising the step of:
- providing a hollow supporting body of a metal or a metallic alloy having a hollow inside section therein;
- introducing into the hollow inside section of the hollow supporting body a liquid into which is mixed a superconducting ceramic powder material comprising an oxidized copper material;
- drying the above liquid, so that the superconducting ceramic material is coated on the inside of the supporting body with a hollow space kept therein;
- wherein the liquid is a solvent for the superconducting ceramic powder material and does not destroy the superconductivity of the superconducting ceramic material coated on the inside of the supporting body;
- and
- firing the supporting body and the ceramic material in an oxidizing atmosphere.
