ABSTRACT:
An electrically resistive track suitable for use as a heating element consists of a thick film including a base metal constituent and a glass constituent. The thick film has in the temperature range of from 20.degree. C. to 600.degree. C. a temperature coefficient of resistance (TCR) less than 0.0050 per degree C. Suitable metal constituents include tungsten, molybdenum, a mixture of nickel and tungsten and a mixture of nickel and chromium.
