  • Patent number: 7463477
    Abstract: A mixed dispersant which can improve the efficiency of dispersing metal powder by effectively adsorbing on the surface of the metal powder and preventing aggregation thereof, and a paste composition and a dispersion method using the same are provided. A multilayer ceramic capacitor (MLCC) is also provided. The mixed dispersant includes a basic dispersant and an acidic dispersant in accordance with the acidity and basicity of nickel metal powder and thus can achieve an optimal dispersion efficiency. An improvement in the dispersion efficiency as such can consequently suppress aggregation of the nickel metal powder during the preparation of a conductive paste composition containing a nickel metal powder, and therefore a larger amount of the nickel metal powder can be used in the paste composition. The increased amount of nickel metal powder allows producing an internal nickel electrode having improved electric properties and mechanical properties during the production of MLCCs.

  • Publication number: 20070012899
    Abstract: A phosphate dispersant which can improve the efficiency of dispersing nickel metal powder by effectively adsorbing on the surface of the metal powder and preventing aggregation thereof, and a paste composition and a dispersion method using the same are provided. A multilayer ceramic capacitor (MLCC) is also provided. The phosphate dispersant can achieve the optimal dispersion efficiency by strongly adsorbing on the surface of the nickel metal powder. An improvement in the dispersion efficiency as such can consequently suppress aggregation of the nickel metal powder during the preparation of a conductive paste composition containing a nickel metal powder, and therefore a larger amount of the nickel metal powder can be used in the paste composition. The increased amount of nickel metal powder allows producing an internal nickel electrode having improved electric properties and mechanical properties during the production of MLCCs.
