ABSTRACT:
A vitreous enamel resistor material comprising a mixture of a vitreous glass frit, an insulating material containing an oxide of zirconium, and a conductive phase of fine particles of tin oxide. The insulating material is selected from the group consisting of zirconia (ZrO.sub.2), calcium zirconate (CaZrO.sub.2), barium zirconate (BaZrO.sub.3) and strontium zirconate (SrZrO.sub.3), and the conductive phase may also contain an additive such as tantalum oxide. An electrical resistor is made from the resistor material by applying the material to a substrate and firing the coated substrate to a temperature at which the glass softens. Upon cooling, the substrate has on the surface thereof a film of glass and insulating material having the particles of the conductive phase embedded therein and dispersed therethroughout. The resistor material provides a resistor having relatively high resistivity as well as rugged physical characteristics.
