Claim 1
Independent Claim
114 words
A METHOD FOR PRODUCING A LAMELLAR STRUCTURE WHICH COMPRISES ASSEMBLING A PLURALITY OF SHEETS, EACH OF WHICH SHEETS CONSISTS ESSENTIALLY OF AT LEAST ONE NOBLE METAL, AND A COMPOSITE CONSISTING ESSENTIALLY OF PARTICLES OF AT LEAST ONE NOBLE METAL AND A PLURALITY OF BODILY SEPARATE MASSES OF FROM 0.25 TO 10 MICRONS IN DIAMETER OF A HARD, REFRACTORY, METAL OXIDE MATERIAL COATED WITH SAID NOBLE METAL, SAID METAL OXIDE CONSTITUTING FROM ABOUT 0.9 PERCENT TO ABOUT 25 PERCENT OF THE COMPOSITE, INTO A STRUCTURE WHEREIN THE COMPOSITE IS DISPOSED BETWEEN ADJACENT NOBLE METAL SHEETS, AND SUBJECTING THE STRUCTURE SO PRODUCED TO HEAT AND PRESSURE FOR A TIME SUFFICIENT TO PRODUCE AN INTEGRATED LAMELLAR STRUCTURE.
