A metal electrode of a ceramic capacitor and a method of forming the same are provided. The method includes mixing metal powders and a barium titanate organic-precursor to obtain precursor powders; adding an adhesive to the precursor powders to obtain a metal slurry; performing a molding process to the metal slurry to obtain a film material; performing a binder burn-out process to the film material to obtain a degumming film; and performing a sintering process to the degumming film to obtain the metal electrode. By mixing specific amount of barium titanate organic-precursor with the metal powders, the barium titanate metallic organic-precursor can be transformed to barium titanate in the following process, and barium titanate can be dispersed between the metals homogeneously. Therefore, electrode continuity can be increased.

This present invention relates to a method of synthesizing copper selenide powder by using a hot-injection method wherein a proper amount of a reducing agent is added to a mixed solution made of copper cationic solution and selenium anionic solution, and the mixed solution is maintained at a temperature of 230&#xb0; C. for 40 minutes to obtain Copper Selenide powder. The Copper selenide powder, which is in the form of CuSe or CuSe, can be synthesized by adjusting the amount of the reducing agent being added to the mixed solution.
