Abstract
A dielectric glass composition consisting essentially on a molar basis of 15-27% ZNO, 8-16% BaO, 40-60% SiO.sub.2, 3-14% Al.sub.2 O.sub.3, 0-5% PbO and 0.5-5% of a metal oxide selected from ZrO.sub.2, up to 2.5% P.sub.2 O.sub.5 and mixtures thereof, the composition being crystallizable and non-reducing when fired at 850.degree.-900.degree. C.
