<p>PURPOSE:To manufacture an oxide superconductive laminate in which a metal base and a superconductive material are not separated each other by laminating a ceramic layer, a precious metal layer and an oxide superconductive material layer on a metal base in said order. CONSTITUTION:An oxide superconductive laminate is composed of an intermedi ate layer consisting of a ceramic layer and a precious metal layer formed on a metal base and an oxide superconductive material layer on said intermediate layers and integrated together thereon. The intermediate layer composed of two layers of ceramic and precious metal acts synergistically on both of the metal base and the oxide superconductive material layer formed on the outer surface. Because of said action, respective layers on the metal base of the oxide superconductive laminate are stabilized, and release or crack is not gener ated even when the same is used in liquid nitrogen which develops superconductive characteristics. Also, the metal base and the superconductive raw material are not reacted at the time of calcination in any kind of superconductive materials. Its superconductive characteristics are higher than those of a single-layer intermediate layer.</p> |
