SILVER POWDER, METHOD FOR PRODUCING SILVER POWDER, PASTE-LIKE COMPOSITION, METHOD FOR PRODUCING JOINED BODY, AND METHOD FOR PRODUCING SILVER FILM

摘要

To provide silver powder capable of producing a dense sintered body by heating at lower temperature than conventional one, and to provide a method for producing silver powder.SOLUTION: In silver powder, in time-of-flight secondary ion mass spectrometry, with respect to a detection amount of Agions, a detection amount of the CHOions is in a range of 0.2 times or more and 1.0 times or less and a detection amount of the CHOions is in a range of 0.005 times or more and 0.02 times or less, in number distribution of a primary particle diameter, a content of primary particles with a particle diameter in a range of 20 nm or more and 50 nm or less is 65% by number or more and a content of the primary particles with a particle diameter in a range of 200 nm or more and 500 nm or less is 3% by number or more.SELECTED DRAWING: None
