Abstract
A glass frit for firing in reducing environments includes an unusually large amount of calcium fluoride melted therein. Also, a copper conductive composition includes the glass frit with an unusually large amount of calcium fluoride. This copper conductive composition may be a paste prepared for screen printing, in which case an appropriate screening agent known to one of ordinary skill may be incorporated, or the composition may be a fired film formed upon a suitable substrate. A high power surge resistor also incorporates the glass frit.
