Characteristics of Ag-Pd-glass composite and Ag-Pd alloy powders prepared by spray pyrolysis

►Ag-Pd (85:15) alloy and Ag-Pd-glass composite powders comprising spherical particles with dense structures were prepared directly by spray pyrolysis at 1100 °C. ►Ag-Pd conductive films formed from the Ag-Pd-glass composite powders had a denser structure than did those formed from the Ag-Pd alloy powders. ►The specific resistances of the conductive films formed from the Ag-Pd-glass composite powders were found to be as low as 12.7 μΩ cm and 4.9 μΩ cm at firing temperatures of 550 °C and 800 °C, respectively.
