Abstract

PURPOSE:To produce a material having a transition point to superconducting state at above the b.p. of liquid N2 by specifying a temp. lowering rate in a cooling stage during sintering in a process for producing an M (a IIIA group element)-Ba-Cu-O type superconducting ceramic material. CONSTITUTION:Raw material powder for an M-Ba-Cu-O type (wherein M is a group IIIA element) superconducting ceramic material, is molded and then calcined to cake in the sintering stage of the ceramic material wherein the cooling after sintering is performed at 125-150 deg.C/hr cooling rate. The cooling rate influences severely on the superconducting characteristics of the ceramic material. By regulating the cooling rate to a value within the range as described above, a superconducting ceramic material having superior superconducting characteristics, namely, a material having higher transition temp. of superconductivity than the b.p. of liquid N2, is obtd.
