Preparation and Performance Characterization of Flake Silver Powder
摘要
Abstract
High sphericity silver powder was prepared using silver nitrate,ammonia water,ethylenediamine,hydrazine hydrate,and Tween-80 as the raw material,complexing agent,reducing agent,and dispersant,respectively.The flake silver powder was produced through mechanical ball milling,using a mixture of ethylene glycol and water as the milling aid.The micro-morphology,average particle size,specific surface area,particle size distribution,tap density,and conductivity of the silver powder milled for different durations were characterized and analyzed using a laser particle size analyzer,scanning electron microscope(SEM),tap density meter,specific surface area analyzer,three-roll mill,and X-ray diffractometer(XRD).The results showed that after 14 hours of ball milling,flake silver powder with an average particle size of 3.79 μm,tap density of 5.05 g/cm³,narrow particle size distribution,good dispersibility,and excellent conductivity was obtained.This flake silver powder can be used for the preparation of conductive pastes.关键词
