摘要： 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.
摘要翻译： 提供一种混合分散剂，其可以通过有效地吸附在金属粉末的表面上并防止其聚集来提高分散金属粉末的效率，以及糊料组合物和使用其的分散方法。 还提供了多层陶瓷电容器（MLCC）。 根据镍金属粉末的酸度和碱度，混合分散剂包括碱性分散剂和酸性分散剂，从而可以获得最佳的分散效率。 因此，在制备含有镍金属粉末的导电性糊料组合物时，分散效率的改善因此可以抑制镍金属粉末的聚集，因此可以在糊料组合物中使用更多量的镍金属粉末。 镍金属粉末的增加量允许制造在生产MLCC期间具有改善的电性能和机械性能的内部镍电极。
