  • Method for preparing dielectric ceramic compositions
    Patent number: 6593263
    Abstract: The present invention discloses a method for preparing Ba(Zn1/3Ta2/3)O3 dielectric ceramic compositions. In accordance with the present invention, by adding a small amount of Al2O3, Ga2O3, ZrO2, or TiO2, which can generate metal ion having an atomic value of 3+ or 4+, the problems occurring during the sintering of BZT due to the volatilization of Zn can be solved. Also, the BZT dielectrics obtained from the present method have a Q value of 200,000, which is higher than the pure BZT, a dielectric constant of 28.5 or more and a resonant frequency temperature coefficient of near 0.
