Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
117 words
THE METHOD OF FORMING A CONDUCTIVE FILM UPON THE SURFACE OF A CRYSTALLINE LAYER OF A HIGH RESISTANCE COMPOUND HAVING A CATION SELECTED FROM THE GROUP CONSISTING OF ZINC, CADMIUM AND MIXTURES THEREOF AND AN ANION SELECTED FROM THE GROUP CONSISTING OF SULPHUR, SELENIUM, TELLURIUM AND MIXTURES THEREOF WHICH METHOD COMPRISES IMMERSING SAID LAYER IN A SOLUTION CONTAING METALLIC IONS WHICH ARE CAPABLE OF REPLACING THE CATION OF SAID COMPOUND AND CAUSING SAID SOLUTION TO REACT WITH SAID COMPOUND BY MAINTAINING SAID LAYER IN SAID SOLUTION AT A TEMPERATURE OF APPROXIMATELY 25*C. TO 150*C. FOR A TIME SUFFICIENT TO ALLOW A CHEMICAL REACTION THEREBETWEEN TO FORM A SURFACE-ADJACENT FILM OF A SUBSTANCE HAVING A LOW ELECTRICAL RESISTANCE.
