This invention discloses a method for preparing electrode slurry material in a ceramic condenser including the following steps: dissolving an organic package material in a solvent then adding ceramic powder and NI powder in the solution for ball mill scattering to prepare a scatter solution with ceramic powder and Ni powder, 2, adding bond solution in said scatter solution to be grinded and scattered. This invention also discloses an internal electrode slurry including (wt): Ni powder: 40-60%, ceramic powder: 2.5-15%, bonder: 2-6%, solvent: 30-55% and organic package material: 0.05-1%, in which, the mean size of Ni powder is between 0.2-1.0mum and that of the ceramic powder is between 0.1-0.4mum. |
