Abstract

Nano-sized Ag-Pd alloy and Ag-Pd-glass composite powders were prepared by flame spray pyrolysis. The Ag-Pd molar ratio was fixed at 70-30. The mean sizes of the Ag-Pd and Ag-Pd-glass powders were 29 and 25nm, respectively. The Ag-Pd alloy powder began to be oxidized rapidly at approximately 365°C and oxidation of alloy powders was finished at 420°C. On the other hand, oxidation of the Ag-Pd-glass composite powders gradually occurred around 400°C and oxidation of the powders was finished at 530°C. The specific resistances of the conducting films formed from the nano-sized Ag-Pd-glass composite powders were 76, 59, 35 μΩ·cm at firing temperatures of 550, 600 and 800°C, respectively.
