In the current work, nano-meter scale Ag particles were analyzed on their sintering properties and on resistivity. The microstructural features on sintering are also examined and the possibility of lowering sintering temperature is discussed. The nano paste composed of 10 nm Ag particles exhibits exothermic reaction both at about 150℃ and at 180℃ depending on the organic medium and the separation of dispersant. Sintering proceeds according to those thermal reactions. For a higher sintering temperature of 250℃ , the electrical resistance and microstructural feature exhibited the best characteristics.
