ABSTRACT:
This invention provides for a porous dielectric composition comprising at least one crystallized glass, at least one non-crystallized glass, and at least one Group IIA metal silicate, the porosity of said composition ranging from about 2% to about 50% by volume open space, the average diameter of the pore spaces in said composition ranging from about 1 to about 30 micrometers. The invention also provides for dielectric pastes and dieletric tapes for providing these dielectric compositions. The invention also provides for a process for making these dielectric compositions. These dielectric compositions are useful in making multilayered circuits, thick film circuits and other electronic components.
