Abstract

Microstructure development and its effects on electrical and mechanical properties were investigated for the ZnO/Ag composites fabricated by Pulse Electric Current Sintering (PECS) method. Two kinds of powder mixtures, ZnO/Ag2O and ZnO/Ag, were used as starting materials. Scanning electron microscopic observation indicated that the fine Ag particulates were homogeneously dispersed within the matrix grains and/or at the grain boundaries for the ZnO/Ag composites prepared by reduction process of Ag2O fine powders. The fracture toughness and hardness increased with increasing Ag volume fraction. On the other hand, the resistivity decreased with increasing Ag content.
