Abstract:The firing atmosphere (air, oxygen, and argon) was found to affect the electrical and mechanical properties of an air-fireable electrically conductive glass-free silver-based thick film. For the optimum firing temperature of 930°C, air results in the lowest resistivity, but a minor amount of pinholes; oxygen results in the largest thickness, the smoothest surface, and no pinhole; and argon results in the highest resistivity, large pinholes, the smallest thickness, vanishing of macroscopic parts of the film, an… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
