ABSTRACT:
Disclosed herein is a composition for electrodes that enables a firing process in air at a temperature of 600° C. or less and does not cause an increase in absolute resistance and a substantial variation of the resistance even when the composition is repeatedly subjected to the firing process. The composition for electrodes comprises: about 5 to about 95% by weight of aluminum powder, the aluminum powder having a particle size distribution of about 2.0 or less as expressed by the following Equation (1) and having D50in the range of about 0.1 μm≦D50≦about 20 μm; about 3 to about 60% by weight of an organic binder; and the balance of a solvent:in-line-formulae description="In-line Formulae" end="lead"?Particle size distribution=(D90−D10)/D50 (1)in-line-formulae description="In-line Formulae" end="tail"?wherein D10, D50, and D90represent particle diameters at 10%, 50% and 90% points on an accumulation curve of a particle size distribution when the total weight is 100%.An electrode and a PDP fabricated using the composition are also disclosed.
