Abstract
PURPOSE: To obtain a superconductor capable of exhibiting the high critical temperature, by constructing the surfaces of many crystal grains containing group IIa and IIIa elements, Cu and O and interfaces of a three-dimensional network structure from components having the higher superconducting critical temperature than that of the interior.
CONSTITUTION: An oxide ceramics based superconductor 1 is constructed from a sintered compact, containing at least one of group IIa elements, such as Ba or Sr, one or more of group IIIa elements, such as La, Y or Sc, Cu and O and having aggregation of many crystal grains 2 and 3. The surfaces 4 and 6 of the above-mentioned crystal grains 2 and 3 and interfaces 7 thereof are constituted of components capable of exhibiting the higher superconducting critical temperature than that of the interiors 8 and 9. Furthermore, the aforementioned high-critical temperature components are formed into a three-dimensional network through pores 5. The above-mentioned sintered compact is obtained by sintering blended powder of the raw materials respectively containing the respective composition components at a temperature below whichever lower temperature of the melting temperature or decomposition temperature of the materials and above a temperature at which the materials can be sintered in air. Thereby the aimed superconductor capable of exhibiting the higher critical temperature than that of a layer perovskite-type superconducting material is obtained.
