ABSTRACT:
A termination material for a vitreous enamel electrical resistor includes a mixture of a glass frit and particles of either molybdenum, tungsten, tantalum or titanium. The termination material is applied to a substrate and fired to melt the glass frit, and then cooled to form a layer of the glass with the metal particles embedded therein. The termination material may be applied to the substrate either before or after the resistance material is applied to the substrate and is particularly useful with vitreous enamel resistance materials which include either a mixture of tantalum nitride and tantalum, a mixture of tungsten carbide and tungsten, or an alloy of copper and nickel.
