ABSTRACT:
An alkali-free composition for making a ceramic dielectric body having a dielectric constant less than 5.0, which is a mixture of finely divided particles consisting essentially of 70-85% wt. silica and 15-30% wt. zinc borate flux. This composition can be used to make green tape and multilayer devices having internal copper conductors such as multilayer capacitors and multilayer interconnects.
