COMPOSITE WITH HIGH DIELECTRICITY

摘要

The BaTiO3 as main component having over 99.5% of purity is mixed with CeO2 and TiO2 to make formula of Ba1-xCe2x/3 TiO3+x/3 (0.02<=x<=0.035). A 0.01-0.09 wt.% of MnO2 is added to the above powder to elevate insulation resistance and dielectric loss coefficient. A composite is prepared by mixing the powder and a binding agent of acrylic analogue to have dielectric constant of 6000-8000 at curie temp. of 60-70 deg.C.
