A Method for Preparing Metal Inner Electrode Paste Having High Dispersibility for Having Super High Capacity Multi Layer Ceramic Capacitor

摘要

The surface used for the second electrode formed inside the high-capacity multilayer ceramic capacitor roughness, to a dry film density, and is excellent in dispersibility metal paste method. Metal powder per 100 parts by weight, ethyl cellulose resin, 3-7 parts by weight of terpineol solvent and 30 to 70 parts by weight of a dispersing agent 0 to 1.5 parts by weight of pre-mix and high viscosity after dispersion, the metal powder per 100 parts by weight of low boiling solvent 30-200 wt. in the step of diluting low road to wealth; Ceramic public fortune, terpineol solvent, any dispersing agent and a pre-mix of any low boiling point solvent and low-viscosity dispersion and by the addition of ethyl cellulose resin binder in the premix, wherein the ceramic public fortune, ethyl cellulose resin, terpineol solvent, any of a dispersing agent and any low-boiling solvent is a low viscosity so that dispersion of ceramic public fortune by weight per 100 parts by weight of ethyl cellulose resin, 1-5 parts by weight, 10-150 parts by weight of terpineol solvent, a dispersing agent 0 to 1.5 parts by weight of low boiling solvent and 0 to 100 parts by weight the step of; Metal powder to the metal powder and the ceramic product public fortune dispersion of 100 parts by weight of ceramic public fortune 10 to 30 parts by weight of mixing and dispersion; Comprising a low-boiling volatile solvent; Viscosity adjusting and vacuum degassing (脫 泡); There is provided a method for producing a metal paste comprising a; and the step of filtering cartridges. The metallic paste is prepared by the above method is improved dispersibility, shows good surface roughness, dry film density and firing shrinkage. ; Metal powder, ceramic public fortune, highly dispersed, metal paste, the internal electrode
