A METHOD OF FORMING A SUPERCONDUCTIVE METALLIC FILM ON A SUBSTRATE WHICH COMPRISES POSITIONING AT LEAST ONE SUBSTRATE WITHIN A CHAMBER, EVACUATING SAID CHAMBER TO A PRESSURE IN THE RANGE OF 1X10**9 TO 5X10**5 MILLIMETERS OF MERCURY, POSITIONING A METALLIC MEMBER CONTAINING A HIGH MELTING POINT SUPERCONDUCTIVE METAL WITHIN SAID CHAMBER, POSITIONING A SECOND LOWER MELTING POINT SUPERCONDUCTIVE METAL WITHIN SAID CHAMBER, HEATING AT LEAST A PART OF SAID FIRST SUPERCONDUCTIVE METAL TO AT LEAST ITS MELTING POINT, EVAPORATING AN INITIAL PORTION OF THE FIRST RESULTING MOLTEN METAL WITHIN SAID CHAMBER THEREBY GETTERING OXYGEN AND OXYGEN CONTAINING COMPOUNDS THEREIN, HEATING SAID SECOND METAL TO ITS EVAPORATION TEMPERATURE; SUBSEQUENTLY EVAPORATING AN ADDITIONAL PORTION OF SAID FIRST MOLTEN METAL AND CONDENSING SAID MOLTEN METAL ON SAID SUBSTRATE, AND COEVAPORATING AT LEAST A PORTIN OF SAID SECOND METAL AND CONDENSING SAID SECOND MOLTEN METAL SIMULTANEOUSLY ON SAID SUBSTRATE IN A RATIO OF 1 TO 3 OF SAID SECOND LOWER MELTING POINT METAL TO SAID FIRST
