Production of copper oxide superconductor

Abstract

Abstract PURPOSE: To obtain a high purity copper oxide superconductor by molding a mixture of copper nitride, an oxidizing agent and yttrium oxide into a pellet and cooling after heating. CONSTITUTION: Copper nitride, an oxidizing agent and yttrium oxide are mixed and the mixture is molded into a pellet. Next, after the pellet is heated, is cooled to obtain the objective superconductor. Usually the mixing is performed for 5-10 min with a mortar and a pestle. A particle having 5-10 μ average diameter is obtained after pulverizing and compressing. Further the heating can be carried out by heating in a Lindberg tube furnace provided with an automatic controller or a Marshall II furnace provided with an euro therm controller. After that, the molded pellet is taken out with the intermittent operation of the furnace and is cooled, for example at a 2°C/min speed to the room temp. of about 20-25°C in general.
