Abstract
A method of producing ceramic superconducting materials such as YBa.sub.2 Cu.sub.3 O.sub.x includes blending together starting materials for the superconducting material. The blend of starting materials are formed into a layer and sintered at a temperature above the peritectic temperature for the superconducting material. Prior to sintering, the starting materials for the superconducting material may be unreacted. The starting materials may also be partially reacted prior to sintering by calcining for a period of time at a temperature which does not result in full reaction of the starting materials to the chemical composition of the desired superconducting material.
Claims14
A method of processing an electromagnetic signal comprising:
- creating a high-temperature superconducting structure comprising a superconducting material wherein the superconducting material has a chemical composition and a peritectic temperature, and the superconducting material is made by:
- (a) blending together starting materials for the superconducting material to produce a blend;
- (b) forming the blend into a layer;
- and (c) heating the layer to a first temperature which is at least as high as the peritectic temperature of the superconducting material;
- wherein at least a substantial portion of the starting materials is not fully reacted to the chemical composition of the superconducting material prior to the heating of the layer to the first temperature;
- placing the high-temperature superconducting structure in an electromagnetic field generated from the electromagnetic signal;
- and
- coupling a signal from the high-temperature superconducting structure.
