摘要：采用液相化学还原法制备了粒径约为５０ｎｍ的铜粉。研究了高分子吸附对铜粉在空气中的稳定性影响及粉末在水溶液中的稳定性。分别采用表面包银和磷化处理的方法，提高了铜粉的抗氧化性能，使５０ｎｍ铜超微粉末能稳定地存在于空气中，磷化处理后铜粉末的氧化温度高于２２０℃。
By using chemical reduction method in aqueous solutions,the ultramicro copper powder with mean diameter about 50nm was prepared.The stability of ultramicro copper powder coated by polymers in the air and that of copper powder stored in distilled water were studied.The oxidation resistance of ultramicro copper powder was much improved and the powder were stabilized in the air by using silver-coating method and phosphating treatment,respectively.Their oxidizing temperatures are beyond 220℃.
