A dielectric composition comprising an admixture of finely divided solids comprising (a) a noncrystallizable glass of which the deformation temperature (Td) is 580 DEG -625 DEG C. and the softening point (Ts) is 630 DEG -700 DEG C., and (Ts-Td) is 50 DEG -75 DEG C., and (b) a refractory which is substantially insoluble in the glass at temperatures of 825 DEG -900 DEG C. |
