ABSTRACT:
A vitreous enamel resistance material comprising a mixture of a vitreous glass frit and fine particles of a metal silicide of the transition elements of Groups IV, V and VI of the periodic chart. The metal silicide may be of molybdenum disilicide (MoSi.sub.2), tungsten disilicide (WSi.sub.2), vanadium disilicide (VSi.sub.2), titanium disilicide (TiSi.sub.2), zirconium disilicide (ZrSi.sub.2), chromium disilicide (CrSi.sub.2) or tantalum disilicide (TaSi.sub.2). The ingredients of the vitreous enamel resistance material are present in the proportion of, by weight, 25 to 90% glass frit and 75 to 10% metal silicide. An electrical resistor is made with the vitreous enamel resistor material of the present invention by coating a ceramic substrate with the vitreous enamel resistance material and firing the coated substrate at a temperature sufficient to melt the glass frit of the vitreous enamel resistance material. Upon cooling, the glass hardens so that the resultant resistor comprises the substrate having on the surface thereof a film of glass with the metal silicide particles embedded in and dispersed throughout the glass film.
