ABSTRACT:
A mixture of powders of barium titanate, a Curie point shifter and a lead titanate-bismuth titanate metal oxide flux which may be fired in a single step at 1800.degree. F. to 2100.degree. F. to produce a dense ceramic body with high dielectric constant. The ceramic is adapted to monolithic, multilayer ceramic capacitors. The low firing temperature minimizes the requirements of high temperature noble electrode material.
