Silver tin oxide(AgSnO2) was fabricated using the conventional powder metallurgy(PM) and a new reactive synthesis(RS) method. Electrical conductivity measurement and X ray diffraction analysis were carried out on bulk AgSnO2 microstructures were determined by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) on the bulk AgSnO2 and its cold drawn wire. The results show that SnO2 particles with finer size and fresh interface can be formed in silver matrix as a result of the fabrication of AgSnO2 electrical contact materials by reactive synthesis. micrometer size tin oxide particles were assembled from nanometer scale particles during the RS process. Compared to conventionally PM processed, AgSnO2 electrical contact materials those fabricated by the RS process have a higher conductivity. and workability as a result of a change of combination states of silver and tin oxide.
