摘要:
Thick flim resistors and conductors compatible with copper and fireable in nonoxidizing atmosphere are provided. The resistors are based on certain hexaboride conductors such as LaB.sub.6 and glasses which are thermodynamically stable to or nonreducible by the hexaborides. Thick film pastes prepared with small particle size hexaboride and certain ethylene-vinyl acetate polymeric vehicles afford resistors having improved temperature coefficient of resistance and coefficient of variation.
