| titleOfInvention | A method of preparing super fine silver powder |
| abstract | The present invention discloses a kind of method for preparing super fine silver powder, AgCl colloid or suspension first is prepared with silver nitrate, ascorbic acid and dispersing agent is added after adjusting pH value, sodium hydroxide or potassium hydroxide solution are added dropwise under ultrasonic wave and mechanical dispersion synergy, most afterwards through separation of solid and liquid, washing, drying, be sieved up to high pure and ultra-fine silver powder；Gained silver powder of the invention is spherical shape or spherical, and average grain diameter is 0.5-3 μm, and particle diameter distribution is narrow, purity is high；Technique is based on chemical reduction method principle, and production cost is low, easy to operate, reaction is controllable, obtain purity is high, particle diameter distribution it is narrow, it is good dispersion can be used as electric slurry silver powder, can be applied to industrialized production. |
