Properties of nano-sized glass powders prepared by flame spray pyrolysis as an inorganic binder in ink-jet printing

Abstract

Silver conducting films are formed by ink-jet printing method from the silver colloidal inks with and without glass powders. Bi-based glass powders with nanometer size prepared by flame spray pyrolysis are used as an inorganic binder. The silver conducting film formed from the ink without glass powders had island structure at a firing temperature of 450°C. On the other hand, the silver conducting film with 5wt% glass content of silver component had clean surface, dense structure, fine grain size and good adhesion property to the glass substrate. The silver conducting films with 1, 3 and 5wt%glass contents had low specific resistivities at a firing temperature of 450°C of 2.6, 2.7 and 3.1 μΩcm, respectively. © 2010 The Ceramic Society of Japan.
