PURPOSE:To dispose a layer of insulating matter on the outer side of superconductive matter so as to obtain a superconductive moulded matter easily without providing a coating layer of insulation. CONSTITUTION:At the outer side of superconductive matter 1 consisting of an alkali soil metal, a rare earth element and a copper oxide is provided a layer of peroxide insulating matter 2 consisting of an alkali soil metal, a rare earth element and a copper peroxide. The composition of the superconductive matter 1 is (A1-xBx)aCubOy, where A is an alkali soil metal, B is a rare earth element, 0<x<1, 1<=a<=4, 1<=b<=4, and (a+b)-1<y<(a+b)+2. The composition of the layer of insulating matter 2 is (A1-xBx)aCubOy', where A is an alkali soil metal, B is a rare earth element, 0<x<1, 1<=a<=4, 1<=b<=4, and (a+b)+2y'). The inside of the superconductive moulded matter is a complete superconductive matter, thereby the superconductive matter is formed easily. |
