Continuous malleable superconductive material which can be machined, rolled and soldered, being the product of sintering at an elevated temperature and pressure of a metal plated powder of a compound QBa2Cu3O7-x wherein Q is yttrium or europium, where x is smaller than one. The metal is advantageously silver and the plating process is one without the use of electricity. A preferred range of silver content is about 5 to 32 weight per cent, and the silver forms an essentially continuous phase in the superconductive material. Sintering can be done at from about 350 DEG and 950 DEG C., with a preferred range of 400 DEG to 900 DEG C. The superconductive material of the invention exhibits transition to zero-resisitivity state and the Meissner effect. |
