VITREOUS ENAMEL MATERIAL FOR ELECTRICAL RESISTORS AND METHOD OF MAKING SUCH RESISTORS

A material for a vitreous enamel electrical resistor includes a mixture of a glass frit and particles of nickel, iron and cobalt. The material is applied to a substrate and fired to melt the glass frit, and then cooled to form a layer of the glass with particles of an alloy of nickel, iron and cobal...

Summary:A material for a vitreous enamel electrical resistor includes a mixture of a glass frit and particles of nickel, iron and cobalt. The material is applied to a substrate and fired to melt the glass frit, and then cooled to form a layer of the glass with particles of an alloy of nickel, iron and cobalt embedded therein. The material provides a resistor having a high temperature coefficient of resistance and which can be self terminating.
