The characteristics of silver-glass composite powders directly prepared by spray pyrolysis from spray solutions with different precursor types of Pb, Si and Ti components were investigated. The composite powders had spherical shape and submicron size irrespective of precursor types of glass material and glass content of the powders. The silver conducting films formed from the composite powders had dense structures irrespective of precursor types of glass material and glass content of the powders. The silver conducting film formed from the composite powders obtained from the spray solution with fumed titania as the source material of the Ti component had the lowest sheet resistance of 2.8 mΩ/sq. The sheet resistances of the silver conducting films changed from 2.8 mΩ/sq to 3.7 mΩ/sq according to the glass content of the composite powders at a firing temperature of 700 °C.
