Title: Manufacture of oxide superconducting wire
Inventor: KUME ATSUSHI
IPC: C01B13/32
Filed: 1987-12-28
Abstract: PURPOSE:To obtain a superconducting wire with high critical current density and excellent mechanical strength by adding acid and a basic material to a solution containing the constituting elements of an oxide superconductor to obtain a neutralized aqueous solution, crushing a mixture obtained by heating it to obtain a homogeneous fine grain powdery material, compressing it to the specific density and heat-treating it. CONSTITUTION:Citric acid or the like is added to an aqueous solution containing the elements constituting an oxide superconductor. A basic material such as ammonia is added into the aqueous solution and neutralizes it to obtain a neutralized aqueous solution with about pH 7. The neutralized aqueous solution is heated to obtain a sponge-shaped mixture. The mixture is crushed with a ball mill or the like to obtain mixed powder, it is dust-molded to produce a dust molded body 1. The molded body 1 is stored in a metal tube 2 to produce a composite body 3. The composite body 3 is shrinkage-processed by a rotary swaging device A, for example. The shrinkage processing is repeated until the density of a core becomes 75% or above of the theoretical density. A wire 13 thus obtained is heat-treated in the oxygen atmosphere to produce an oxide superconducting wire.
