Low Sintering Temperature

The sintering temperature of BaTiO3powder was reduced to 950°C due to the Bi2O3-LiF-CaF2addition.Excellent densification was achieved after sintering at 950°C for 10h. The low sintering temperature of newly developed capacitor materials allows a co-firing with pure silver electrodes.The dielectric constant and the temperature stability of the dielectric constant satisfied the X9R standard, which dielectric properties of were ε25°C1115, ΔC/C25°C±12% (55~200°C), tanδ1.5% (25°C).

Low Sintering Temperature

The sintering temperature of BaTiO3 powder was reduced to 870°C due to the H3BO3-ZnO-Bi2O3 addition.Excellent densification was achieved after sintering at 870°C for 15h. The low sintering temperature of newly developed capacitor materials allows a co-firing with pure silver electrodes.The dielectric constant and the temperature stability of the dielectric constant satisfied the X7P requirements, which dielectric properties of were ε25°C≥ 2800, εr/εr25°C≤±10% (–55~125°C), tanδ≤1.5% (25°C).
