SPHERICAL SILVER POWDER AND METHOD FOR PRODUCING SAME

摘要

While a water reaction system containing silver ions is irradiated with ultrasonic waves to cause cavitation therein, a reducing agent containing solution, which contains an aldehyde as a reducing agent, is mixed with the water reaction system to deposit silver particles, the solid-liquid separation of which is carried out, and thereafter, the separated silver particles are washed and dried to produce a spherical silver powder which has a closed cavity in each particle thereof.

主权项

1. A method for producing a spherical silver powder, said method comprising the steps of:
preparing a water reaction system containing silver ions; preparing a reducing agent containing solution which contains an aldehyde as a reducing agent; and depositing silver particles by reduction by mixing the reducing agent containing solution with the water reaction system while causing cavitation in the water reaction system.
