Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
148 words
A METHOD OF PRODUCING A TRANSPARENT ELECTROCONDUCTIVE TIN OXIDE FILM HAVING A HAZE FACTOR LESS THAN ONE PERCENT AND BEING CAPABLE OF INTIMATE ELECTRICAL CONTACT WITH A CERAMIC SILVER BUS BAR ON A SURFACE OF A CERAMIC BASE, SAID SURFACE HAVING SUBSTANTIALLY THE SAME CHEMICAL COMPOSITION AS SAID BASE, WHICH COMPRISES HEATING THE SURFACE TO A FILM FORMING TEMPERATURE AND APPLYING TO THE HEATED SURFACE A COMPOSITION HAVING A PH BETWEEN 4.5 AND 7 AND CONTAINING AN ORGANIC TIN COMPOUND, HCL, AND AN IONIZABLE FLUORINE CONTAINING COMPOUND, SAID HCL CONCENTRATION BEING UP TO 4 PERCENT BY WEIGHT BASED ON THE WEIGHT OF TIN AND SAID SURFACE BEING HEATED TO A FILM FORMING TEMPERATURE ABOVE 400*F. AT WHICH THE HCL COMPONENT PROVIDES LOWER RESISTIVITY TO THE ELECTROCONDUCTIVE FILM THAN SAID FILM FORMING COMPOSITION CONSISTING OF SAID ORGANIC TIN COMPOUND AND AN IONIZABLE FLUORINE CONTAINING COMPOUND AS THE ESSENTIAL INGREDIENTS.
