Abstract
Powders of barium titanate, of an alkaline-earth-zirconate and of a cadmium containing glass are mixed with an organic binder to form a body that is subsequently fired at from 1800.degree. F to 2050.degree. F to make a glass-reacted-ceramic dielectric having a glass phase intermixed with a single titanate-zirconate phase. The omission of the conventional calcining step to obtain the single phase titanate-zirconate results in a substantial cost saving.
