Nano-sized silver powders coated with Pb-based glass material with glass transition temperature of 504°C are prepared by high temperature flame spray pyrolysis. The mean size of the composite powders is 42nm. The thickness of glass layer covering the nano-sized silver powder is 1.4nm. The silver conducting films formed from the composite powders with 3 and 5wt.% glass contents have fine grain sizes...
Conductive silver–glass composite powders, which are promising candidates for novel electrode materials, were prepared by spray pyrolysis. Composite conducting powders had a core–shell structure, which was the same as that of glass-coated silver powders. The composite powders with a mean size of 0.63μm had spherical shape and non-aggregation characteristic. Even at a low firing temperature of 450°C,...
