摘　　要：研究了在碱性条件下,以Tween20为分散剂,用葡萄糖还原硝酸银水溶液制备超细银粉的方法,探讨了分散剂用量、温度、反应物浓度等因素对银粉粒径的影响,用X衍射和透射电镜对所得银粉进行了表征。The preparation of ultrafine silver powder by reducing silver nitrate with glucose in basic solution and polyxyethylene sorbitan monolaurate ( Tween 20 ) as dispersant was investigated. The influences of quantity of Tween 20,and temperature and concentration of reactant on silver particle size were discussed. The silver powders were characterized by XRD and TEM.
