This paper discusses the status of thick conductive films formed by firing in air. The metals under study include nickel, chromium, aluminum and copper. The properties of the films are presented for firing temperatures ranging from 580 to 850 degrees C. Compatibility with various dielectrics and glasses have been studied. Multilayer wiring seems promising. Potential uses on porcelain enamelled steel, window glass and alumina substrates seem feasible.

Initial studies have been made of compatibility with thick film ruthenium-based resistors. Some preliminary information on termination resistance and other properties observed in such combinations is presented.

Possible applications in gas discharge displays for cathodes and conductor runs are discussed. Potential uses may include economical ground planes, solar cell electrodes, varistor and thermistor terminations, and resistance thermometers.
