Abstract
A novel method for manufacturing tabular silver nanoparticles with high productivity and high reproducibility. The present invention provides a method for manufacturing silver nanoparticles including a first step of preparing a silver ion aqueous solution containing a crystal habit modifier as a starting solution, a second step of adding a reducing agent to the starting solution with stirring to yield an aqueous dispersion of fine silver crystals, and a third step of adding an oxidizing agent to the aqueous dispersion with stirring. The oxidizing agent is preferably added such that the solubility of metal silver in the aqueous dispersion is optimized at an appropriate time in the third step.
