Electrode forming composition comprising aluminum powder with controlled particle size distribution and size and electrode manufactured using the same

摘要

Disclosed herein is a composition for electrodes that enable a firing process in air at a temperature of 600 DEG 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 D50 in the range of about 0.1 mum=D50=about 20 mum; about 3 to about 60% by weight of an organic binder; and the balance of a solvent; in the formula (I), wherein D10, D50, and D90 represent 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. The grain size distribution is (D90-D10)/D50 (1).
