PURPOSE:To obtain a wire rod having highly stable superconducting characteristics and a freely selectable shape by depositing starting material powder of a compound oxide superconducting material dispersed in a liquid contg. an ionized carrier to a surface of a substrate by electrodeposition, then sintering the powder after evaporating the carrier. CONSTITUTION:At least a kind of starting material powder consisting of (i) constituting elements of a compound oxide for said superconducting material, (ii) compds. contg. at least one kind of constituting elements for said compound oxide, or (iii) that obtd. by sintering (i) or (ii) and pulverizing a sintered body obtd. thereby, is used. The starting material powder is dispersed in a liquid contg. an ionized carrier such as a soln. of methacrylic resin in an org. solvent. A substrate and an electrode confronting the substrate are dipped in the liquid, and said ionized carrier is deposited to the surface of the substrate by impressing a DC voltage across the substrate and the electrode. In this case, the substrate may be formed to an optional shape such as coil, etc. Then, the carrier is evaporated by heating off the substrate to which the starting material powder has been deposited, then the starting material powder layer is sintered to obtain thus a compound oxide layer. |
