Claim 1
Independent Claim
145 words
A METHOD OF PRODUCING NICKEL METAL FOIL BY THERMAL DECOMPOSITION OF NICKEL CARBONYL WHICH COMPRISES THE STEPS OF PROVIDING A CLOSED GASEOUS METAL PLATING CHAMBER, CONTINUOUSLY MOVING AN ENDLESS METAL BELT THROUGH SAID CHAMBER, OXIDIZING THE SURFACE OF SAID ENDLESS METAL BELT OF SUBJECTING THE SAME TO A HEATED OXIDIZING CHAMBER ATMOSPHERE, REMOVING OXYGEN FROM THE PLATING CHAMBER BY PASSING INERT GAS THERETHROUGH, THEREAFTER CONTACTING SAID MOVING OXIDIZED BELT SURFACE WITH HEATDECOMPOSABLE GASEOUS NICKEL CARBONYL, RAISING THE TEMPERATURE OF SAID ENDLESS MOVING METAL BELT TO BETWEEN ABOUT 300 TO 400* F. AND CIRCULATING SAID HEAT-DECOMPOSABLE GASEOUS NICKEL CARBONYL IN CONTACT THEREWITH TO CAUSE THE GASEOUS METAL COMPOUND TO DECOMPOSE AND DEPOSIT NICKEL METAL ONTO THE OXIDIZED METAL BELT SURFACE AS A THIN METAL FILM, AND STRIPPING THE THUS DEPOSITED NICKEL METAL FILM FROM THE OXIDIZED METAL BELT AS A CONTINUOUS SHEET OF NICKEL METAL FOIL.
