ABSTRACT:
A ceramic composition for forming a ceramic dielectric body having a dielectric constant of less than about 4.2. The composition comprises a mixture of finely divided particles of 25-50 vol. % borosilicate glass and 50-75 vol. % high silica glass. The composition can be used with a polymeric binder to produce an unfired green tape which is co-fireable with high conductivity metallurgies such as gold, silver and silver/palladium.
