Abstract
A method and apparatus are disclosed for the manufacture of a sheathed superconducting ceramic strip. The apparatus includes a chill wheel and metal casting apparatus wherein means are provided within the metal casting apparatus to cause oxygen to react with molten metal, comprising the base alloy from which a superconducting ceramic is formed, in a controlled manner. Strips of superconducting ceramic partially sheathed in the molten metal emerge from the metal casting apparatus and are engaged by the chill wheel, which solidifies the molten metal to form a continuous strip.
