    Abstract: A high Tc superconducting ceramic material is produced by a method in which a mixture of chemicals in suitable amounts is compacted into a desired form. The compacted mixture is then fired and, at the same time, an electric current is caused to pass through the compacted mixture in a predetermined direction. By virtue of the passage of the current through the material during firing, the orderliness of the molecular arrangement is enhanced and an elevated transition temperature Tc is obtained.

    Abstract: Polycrystalline high-T.sub.c superconductors of the formula M.sub.m E.sub.e RO.sub.x, which contain grains which are crystallographically aligned to the greatest possible extent, where M is at least one trivalent element such as a lanthanide element, E is at least one divalent element such as an alkaline earth element and R is at least one transition metal such as Cu, and x denotes the proportion of oxygen, are obtained by substituting a part of the alkaline earth element by a foreign element, preferably an alkali-metal element, which is no longer present in the product after the reaction sintering and sintering except for contents in the ppm to parts per thousand range and brings about the orientation effect. This produces a material which contains a slight deficit of E and optionally M, has an unaltered critical temperature and is substantially more resistant to external agents than equivalent known materials. A post-treatment in a stream of air or oxygen is unnecessary. Single crystals having relatively large dimensions can also be produced in a corresponding manner.
