Abstract
A ceramic composition for dielectrics, consisting essentially of an inorganic dielectric material including at least one electrically insulating glass and at least one organic binder, and further comprising at least one inorganic peroxide. The inorganic peroxide serves to facilitate burnout or removal of the organic binder during firing of the ceramic composition and minimizes the content of residual carbon in the fired ceramic composition. The inorganic peroxide is preferably selected from the group consisting of calcium peroxide, strontium peroxide, barium peroxide, zinc peroxide and cadmium peroxide, and present preferably in an amount of 0.1-40% by weight. Also disclosed is a process of manufacturing a ceramic circuit board using the ceramic composition stated above.
