Abstract
The present invention is a method of producing highly crystalline silver microparticles by a reduction reaction, which comprises precipitating the silver microparticles by reacting a silver solution containing at least silver ions and a reducing agent solution containing at least a reducing agent by a continuous wet reduction method, wherein a reduction rate from the silver solution to the silver microparticles is 99% or more; an average primary particle diameter of the silver microparticles is 100 nm or more and 1,000 nm or less; and an average crystallite diameter relative to the average primary particle diameter of the silver microparticles is 80% or more. Even highly crystalline silver microparticles having 95% or more of the ratio (d/D) of the average crystallite diameter (d) relative to the average primary particle diameter (D), that is, silver microparticles in which almost all silver microparticles are single crystals, can be continuously produced by a liquid phase method, by the present invention.
