摘要
随着电子信息和新能源产业的迅速发展,对新型高端功能金属材料的需求更加迫切。超细高纯铜粉具有低烧结温度、低软化温度、高比表面、高导电导热等优异特性,因而成为了PCB互连、冶金风电润滑等领域的关键材料。然而,制备微纳米铜粉仍然面临困难。对目前微纳米铜粉的制备工艺进行了梳理和分析,讨论了不同制备方法的原理和优缺点,并对其研究动态进行总结;对于微米级铜粉的制备,目前主要采用电解法和雾化法等成熟工艺路线,但制备得到的铜粉同时是调控形貌和纯度仍然存在较大困难;而对于纳米级铜粉的制备,目前主要通过液相还原法获得,可以满足高纯度小尺寸的要求,但需要克服工程化批量生产的难题。
With the rapid development of the fields of electronic information and new energy industries,the demand for new high-end functional metal materials has become more urgent.The micro-nano high purity copper powder has excellent characteristics,such as low sintering-temperature,low softening-temperature,high specific-surface,high electrical and thermal conductivity,and thus has become a key material in PCB interconnect,metallurgy and wind power fields.However,the preparation of micro-nano copper powders has still some difficult problems.In this paper,different preparation processes for micro-nano copper powders are analyzed,as well as their advantages and disadvantages.In the preparation of micron-sized copper powders,both electrolysis and atomization method are mainly adopted,but the purity of the copper powders obtained from the preparation is low.For the nano-sized copper powders,the liquid-phase reduction method is mainly adopted,which can meet the requirements of high purity and small size,while the difficulties of engineering mass production are needed to overcome.
