Uncapped silver nanoparticles synthesized by DC arc thermal plasma technique for conductor paste formulation
Source abstract
Abstract
Uncapped silver nanoparticles were syn- thesized by DC arc thermal plasma technique. The synthesized nanoparticles were structurally cubic and showed wide particle size variation (between 20- 150 nm). Thick film paste formulated from such uncapped silver nanoparticles was screen-printed on alumina substrates and the resultant 'green' films were fired at different firing temperatures. The films fired at 600 C revealed better microstructure prop- erties and also yielded the lowest value of sheet resistance in comparison to those corresponding to conventional peak firing temperature of 850 C. Our findings directly support the role of silver nanopar- ticles in substantially depressing the operative peak firing temperature involved in traditional conductor thick films technology.
