Abstract: A manufacturing method of paste for plasticized electrode, using nano silver particles is provided to save the fuel by lowering a temperature necessary for plasticizing due to sinterability at the temperature lower than the melting point of the inherent metal. A manufacturing method of paste for plasticized electrode, using nano silver particles comprises a step for synthesizing the silver particle of nano-size consisting of silver powder of nano-size 5~20wt%, silver powder 50~65 wt%, lead-free Bi-based frit glass 3~9wt%, and a vehicle 21~27 wt% which is an organic solvent; and a step for mixing the synthesized silver particle of nano-size with the silver powder.

Abstract: A low temperature cofired paste composition containing nanosilver particles and a manufacturing method of the conductive thick film using the same are provided to manufacture the low temperature cofired paste using silver particles of nano size, to reduce the waste of material and to solve the disadvantage that the precision of the electrode morphology is decreased. A low temperature cofired paste composition containing nanosilver particles comprises silver powder of nano-size, glass powder, and vehicle as a solvent in a mass rate of 80:1:19. A manufacturing method of the conductive thick film using the low temperature cofired paste composition comprises a step for screen-printing the paste composition on an alumina substrate with the screen mask; a step for drying the paste composition at 120deg.C for 20 minutes to remove the vehicle so as to form a thick film; and a step for heat-treating the thick film at 250~450deg.C for 15 minutes.
