Abstract
A method of making a composite high-temperature superconducting wire in which a layer of a superconductive oxide is coated onto a refractory core by melting a zone of the layer uniformly all around the core as the core is drawn through the focus of a reflector having the shape of a paraboloid of revolution while directing onto the reflector a collimated beam of an energy sufficient to melt the layer. The melted layer is cooled with a substantially radially symmetrical thermal gradient to form the superconducting oxide ceramic layer on the core with radially-directed growth of columnar grains of the superconducting oxide ceramic.
