Abstract
An oxygen source-containing composite nanometal paste including at least composite nanometal particles, in which an organic coating layer is formed around a submicron or smaller silver core, and an oxygen source, which feeds oxygen contributing to pyrolysis at a pyrolysis temperature range in which the organic coating layer is pyrolyzed. The oxygen source comprises an oxygen-containing metal compound, and the oxygen content of the oxygen source is within a range of 0.01 mass % to 2 mass % per 100 mass % of the composite nanometal particles.
Claims7
An oxygen source-containing composite nanometal paste comprising at least composite nanometal particles in which an organic coating layer is formed around a submicron or smaller silver core, and an oxygen source for feeding oxygen contributing to pyrolysis at a pyrolysis temperature range in which said organic coating layer is pyrolyzed, wherein said oxygen source comprises an oxygen-containing metal compound, wherein said oxygen-containing metal compound comprises one or more members selected from the group consisting of silver peroxide and copper suboxide, and wherein the oxygen content of said oxygen source exists within a range of 0.01 mass % to 2 mass % per 100 mass % of said composite nanometal particles.
An oxygen source-containing composite nanometal paste comprising at least composite nanometal particles in which an organic coating layer is formed around a submicron or smaller silver core, a metal filler, and an oxygen source for feeding oxygen contributing to pyrolysis at a pyrolysis temperature range in which said organic coating layer is pyrolyzed, wherein said oxygen source comprises a surface oxidation layer which is formed on a surface of said metal filler, wherein said surface oxidation layer comprises copper suboxide, and wherein the oxygen content of said oxygen source exists within a range of 0.02 mass % to 2 mass % per 100 mass % of said composite nanometal particles.
