    The invention discloses a barium titanate based ceramic capacitor medium. Considering the weight of BaTiO3 is 1, adding 0.5-2% Nb2O5, 6-8% MgO, 3-5% Gd2O3, 0.02-0.1% MnCO3, 0.2-2% Ag2O and 4-6% glass powder. The process includes the following steps: mixing the material, taking ball milling, drying, taking part of the material to take second ball milling, drying, graining, pressing into disc shape green compact, sintering in 1125-1135 degree centigrade, keeping temperature for 3-5 hours. The ceramic capacitors have the features of low power consumption, and high temperature stability, and ultra large capacity.
