Abstract

PURPOSE:To efficiently obtain a superconducting material capable of producing superconducting products having excellent superconducting characteristics, by alternately coating the surface of each particle containing copper on the surface layer side with one of specific two kinds of element oxides to form two or more layers of at least one thereof and firing the resultant composite material. CONSTITUTION:The surface of each copper particle 1 in copper powder is coated with an oxide of a group IIA element, such as Ba, Sr or Ca, of the periodic table to form the first coating layer 2. The surface of the first coating layer 2 is then coated with an oxide of a group IIIA element, such as Y, Sc or La, of the periodic table to form the second coating layer 3. Thereby the oxide of the group IIIA element of the periodic table and oxide of the group IIIA element of the periodic table are alternately coated to form two or more layers of one or both of the coating layers consisting of the oxides of the above-mentioned two kinds of elements and provide a composite material 6, which is subsequently fired in oxygen atmosphere to initiate chemical reaction therein and afford superconducting particles. The obtained superconducting particles are aggregated to afford a powdery superconducting material. Alternatively, the obtained powder is suitably subjected to pressing treatment to provide a superconducting material of a given shape.
