ABSTRACT:
Flake silver powders which have a chemisorbed monolayer of organic dispersing agent such as oleic acid on the surfaces and process for their preparation are provided. Such silver powders can be formulated into thick film pastes at above 85% solids levels at relatively low viscosities. Pastes so obtained, when printed and fired, result in films of excellent conductive efficiency.
