  • Dielectric pastes and tapes, and metal substrates coated therewith
    Patent number: 5998036
    Abstract: The present invention relates to dielectric materials which may be used in the manufacture of, e.g., low profile heaters. Such dielectric materials comprise at least about 50% of a glass composition having about 35-50% SiO.sub.2, about 30-40% of an alkaline earth metal oxide selected from the group consisting of CaO, MgO, and SrO, about 13--22% Al.sub.2 O.sub.3, and about 0-10% B.sub.2 O.sub.3, the percentages being weight percentages based on the weight of the total glass composition. Certain dielectric compositions of the disclosure have a linear thermal expansion coefficient in the range of about 6.0 to 9.0 ppm/.degree. C.
