Description |
The microstructure vis-a-vis electrical transport behavior of Ag-Cd and Ag-Sn binary alloys in the temperature range 70-300 K has been studied. The 22.2 wt.% Cd and 29.4 wt.% Cd alloys were both found to have a single-phase structure made of solid solution of Ag. The lattice parameter however increased with increasing Cd content in the alloy. The microstructure of 17.7 wt.% Sn and 23.5 wt.% Sn alloys however is made of two phases Ag4Sn and Ag3Sn. The resistivity of Ag-Cd alloys increased with increasing Cd content and the temperature coefficient of resistivity (TCR) decreased to 1560 ppm K-1 for the 29.4 wt.% Cd alloy compared to 4100 ppm K-1 for pure Ag. The lowest TCR however was obtained for the 17.7 wt.% Sn alloy, 375 ppm K-1, which has a room temperature resistivity of 23.93 RQ cm. (C) 2003
