Claim 1
Independent Claim
99 words
A METHOD OF FORMING A SUPERCONDUCTIVE V3GA 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 METAL MEMBER CONTAINING VANADIUM WITHIN SAID CHAMBER, POSITIONING A GALLIUM METAL WITHIN SAID CHAMBER, HEATING AT LEAST A PART OF SAID VANADIUM METAL MEMBER TO AT LEAST ITS MELTING POINT, EVAPORATING AN INITIAL PORTION OF THE RESULTING MOLTEN VANADIUM METAL WITHIN SAID CHAMBER THEREBY GETTERING OXYGEN AND OXYGEN CONTAINING COMPOUNDS THEREIN, HEATING SAID GALLIUM METAL TO ITS EVAPORATION TEMPERATURE,
