摘要： Provided is a silver conductive film, a thin film of silver comprising a sintered layer of silver particles having a mean particle size DTEM of at most 100 nm. Its specific resistance is at most 5 μΩ·cm, the ratio of the voids in the sintered layer is at most 3/μm2, and the film has a texture structure with a surface roughness Ra of from 10 to 100 nm.

摘要： Provided is a silver micropowder coated with a protective material and capable of more drastically reducing the sintering temperature than before. The silver micropowder comprises silver particles processed to adsorb hexylamine (C6H13—NH2) on the surfaces thereof and having a mean particle diameter DTEM of from 3 to 20 nm or an X-ray crystal particle diameter DX of from 1 to 20 nm. The silver micropowder has the property of forming a conductive film having a specific resistivity of not more than 25 μΩ·cm when it is mixed with an organic medium to prepare a silver coating material and when a coating film formed of it is fired in air at 120° C. Even when fired at 100° C., it may form a conductive film having a specific resistivity of not more than 25 μΩ·cm. The silver micropowder can be produced by mixing a silver particle dispersion, as monodispersed in an organic medium, of silver particles coated with a primary amine A having an unsaturated bond and having a molecular weight of from 200 to 400, and hexylamine, and then keeping the mixture at 5 to 80° C. with stirring to thereby form precipitated particles.
