THE METHOD OF FORMING AN ELECTRIC CAPACITOR WHICH COMPRISES: CONTINUOUSLY ROLLING A FLEXIBLE LAMINATE COMPRISING A METALLIX LAYER AND AN INSULATING LAYER UPON A ROTATABLE DRIVEN MANDREL WITHIN AN EVACUATED ENCLOSURE TO FORM A CYLINDRICAL BODY HAVING A METALLIC OUTER SURFACE: EVAPORATING A DIELECTRIC MATERIAL CONSISTING ESSENTIALLY OF AMORPHOUS ZINC SULFIDE CONTAINING 0.01 TO 10.0 WEIGHT PERCENT OF MAGNESE AND SELECTIVELY DIRECTING THE VAPORS THEREOF TO A FIRST PORTION OF SAID CYLINDER FOLLOWING THE POINTS AT WHICH THE LAMINATE FIRST CONFORMS TO THE CYLINDRICAL SHAPE OF THE BODY TO DEPOSIT THEREUPON A THIN LAYER OF THE DIELECTRIC; AND SMULTANEOUSLY EVAPORATING AN EASILY VOLATIZABLE METAL AND SELECTIVELY DIRECTING THE VAPORS THEREOF TO A SECOND PORTION OF SAID CYLINDER ANGULARLY DISPLACED IN THE DIRECTION OF ROTATION OF THE BODY FROM SAID FIRST PORTION TO DEPOSIT A THIN METALLIC LAYER UPON SAID DIELECTRIC LAYER.
