ABSTRACT:
A vitreous enamel resistor, and method of making the same comprising the steps of applying to the surface of a substrate and firing a mixture of glass frit and particles of a precious metal oxide such as iridium oxide, ruthenium oxide, and mixtures thereof. The mixture is fired in a neutral, inert, or reducing atmosphere for a time and at a temperature resulting in a controlled partial dissociation of the oxide and softening of the glass frit. When cooled, a resistor is provided having a glass film with conductive particles therein strongly bonded to the substrate. The resistor produced can be terminated by the use of electroless plating.
