摘要： A superconductive material is in composition expressed as (Y 0.33 Ba 0.67 ) a Cu b (OF) c . The usual a , b and c are so selected as to satisfy a relation expression ax (mix valence of A) + bx (mix valence of B) = cx (mix valence of C).

摘要： This invention provides a method for producing an oxide superconducting material of a layered perovskite structure comprising Cu and O as basic constituting elements which has a uniform texture and is markedly high in sintered density and current density. This method comprises previously reacting CuO as one raw material with a carbonate, an oxide or a mixture thereof as another raw material to produce an inter­mediate product or intermediate products containing Cu and O and then finally reacting these intermediate products with each other (in case two or more inter­mediate products are produced) or the intermediate product with other raw material (in case only one intermediate product is produced) to produce an oxide of layered perovskite structure.
