摘要： The present invention relates to a sintered ceramic wire.Ceramic materials, such as A1N, Si.sub.3 N.sub.4 and Al.sub.2 O.sub.3, have various superior characteristics including heat-resistance, and sintered ceramic materials have been of interest as superconducting materials of high critical temperatures.However, various disadvantages are involved in the formation of the sintered ceramic materials as thin wires, and in the practical use thereof.The present invention elminates such disadvantages to provide a thin and long sintered ceramic wire having sufficient strength and toughness to avoid breakage.A sintered wire is made by placing powders of metal oxides, precursors of the desired sintered material, having oxidation potentials less than that of copper, in a tube of a high temperature oxidation-resistant metal. This product is worked to its final size and a sintering step is performed. The method is satisfactory for manufacture of ceramic superconductors.
