    摘要: A method of forming a distortion-free circuit whereby a conductive composition is applied to at least one layer of green ceramic tape. The conductive composition formulation is based on total composition, conductive powder selected from Ag, Pd, Pt and mixtures thereof and 0.5 to 1.5 wt. % boron; wherein a and b are dispersed in organic medium. The green tape formulation is, based on total composition, 25-50 wt. % glass composition comprising, based on mole %, 50-67% B2O3; 20-50% alkaline earth metal oxide; 2-15% rare earth oxide and 0-6% alkali metal oxide and 0-10% Al2O3; 50-75 wt. % refractory oxide and organic polymeric binder. The assemblage is fired to form a distortion-free circuit.

    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.
