ABSTRACT:
A paste for forming a thick film conductor of a base metal on a non-conductive substrate comprises a base metal powder (particularly nickel) which ordinarily would oxidize when fired in air, boron powder and a vehicle. In one embodiment, the paste may also contain glass frit. By proper selection of the composition, in particular the amounts of boron and glass frit, a base metal conductor can be formed which strongly adheres to the substrate and has excellent conductive properties. Ranges of compositions are disclosed within which the pastes can be fired in air and produce conductive thick films and outside which conductive properties are inferior and/or the bond strength is unsatisfactory.
