Study on Low-Temperature Conductive Silver Pastes Containing Bi-Based Glass for MgTiO(3) Electronic Power Devices

Low-temperature lead-free silver pastes deserve thorough investigation for sustainable development and application of MgTiO(3) ceramics in electronic devices. In this study, a series of Bi(2)O(3)-B(2)O(3)-ZnO-SiO(2)-Al(2)O(3)-CaO glasses with suitable softening temperatures were prepared via melt qu...

description Low-temperature lead-free silver pastes deserve thorough investigation for sustainable development and application of MgTiO(3) ceramics in electronic devices. In this study, a series of Bi(2)O(3)-B(2)O(3)-ZnO-SiO(2)-Al(2)O(3)-CaO glasses with suitable softening temperatures were prepared via melt quenching using a type of micrometer silver powder formed by silver nanoparticle aggregates. The composite pastes containing silver powder, Bi(2)O(3) glass powder and an organic vehicle were then screen-printed. The effects of glass powder concentration and sintering temperature on the microstructure of the surface interface were also investigated. The results showed that the silver paste for microwave dielectric ceramic filters (MgTiO(3)) possessed good electrical conductivity (2.28 mΩ/□) and high adhesion (43.46 N/mm(2)) after medium temperature (670 °C) sintering. Thus, this glass powder has great application potential in non-toxic lead-free silver pastes for metallization of MgTiO(3) substrates.
