Abstract

This invention relates to improved powder compositions useful for forming resistors on dielectric substrates; the compositions comprise certain polynary oxides of silver and/or copper ions having a pyrochlore-related crystal structure, plus dielectric material, and 1-10% copper powder. Also dispersions thereof and resistors made by firing these compositions.
