Title: METHOD FOR PRODUCING SILVER NANO-PARTICLES
Abstract:
The present invention provides a method for producing silver nano-particles that can produce silver nano-particles with a narrow particle size distribution in large amounts in a short time from a highly viscous silver oxalate-amine complex. This method for producing silver nano-particles comprises: a mixing step for mixing an amine with silver oxalate to obtain a silver oxalate-amine complex in which the amine is coordinated with the silver oxalate; and a heating step for heating the silver oxalate-amine complex by irradiating the same with microwaves to reduce the silver oxalate-amine complex. The amine comprises at least one kind of compound selected from alkylamines and/or alkoxyamines.
