HIGH CRYSTALLINITY NANO-SILVER PARTICLE SLURRY AND ITS PRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide high crystallinity nano-silver particle slurry of fine particles having a sharp particle size distribution and high crystallinity, and to provide its production method. SOLUTION: The high crystallinity nano-silver particle slurry comprises high crystallinity nano-silver particles, and does not comprise water. In the high crystallinity nano-silver particles, the average particle diameter DTEMaccording to TEM (transmission electron microscope) observation is <100 nm, and the coefficient of variation obtained by dividing the standard deviation of the particle size distribution by the average particle diameter DTEMaccording to TEM observation is≤0.25. In the method for producing high crystallinity nano-silver particle slurry, a silver salt is dissolved in a nonaqueous reducing solvent, so as to produce a reaction liquid, and thereafter, silver ions in the reaction liquid are reduced in a microreactor, thus the high crystallinity nano-silver particle slurry which comprises high crystallinity nano-silver particles and does not comprise water is produced.
