Abstract: An electron emissive composition comprises a barium tantalate composition in an amount of about 50 to about 95 wt% and a ferroelectric oxide composition in an amount of about 5 to about 50 wt%, wherein the weight percents are based on the total weight of the barium tantalate composition and the ferroelectric oxide composition. A method for manufacturing an electron emissive composition comprises blending a barium tantalate composition in an amount of about 50 to about 95 wt% with a ferroelectric oxide composition in an amount of about 5 to about 50 wt% to form an electron emissive precursor composition, wherein the weight percents are based on the total weight of the barium tantalate composition and the ferroelectric oxide composition and sintering the composition at a temperature of about 1000°C to about 1700°C.
