低松装密度化学还原超细银粉生产

The Production Process of Low Apparent Density Superfine Silver Powder by chemical Reduction Method

摘要：采用液相化学还原法，以甲醛为还原剂、高分子有机物为分散保护剂，将硝酸银溶液与还原性溶液混合生产低松装密度超细银粉，对其生产工艺的机理与特点进行了分析探讨，并对比介绍了其应用性能。

Low apparent density superfine silver powder was prepared by reducing the silver nitrate with formol under the presence of rosin dispersant and cladding. The mechanism and trait of the production process was analyzed and discussed. Also the application performance of the silver powder have been introduced by contrast.
