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.

Method of producing an electromagnetic signal

A coating device for use in coating circular cross-sectioned substrates has a semi-circular doctor blade. The coater may also have a plate for holding axially symmetric substrates which can be rotated about an axis. A groove in the plate centers the substrate on the plate for rotation. The doctor blade is located adjacent to the substrate such that when the plate and substrate are rotated, the doctor blade applies a uniform thickness of coating to one side of the substrate. After one side of the substrate has been coated, the other side is coated by placing the substrate coated side down on a plate with a larger groove to accommodate the increased size of the substrate due to coating.
