去年,西德汉堡北德意志粉末冶金公司已批量试生产提供了从小于0.5微米到最大为10微米的各种粒径的超细铜粉。铜粉采用一种新的化学工艺(注册专利)制造,铜粉的性能如下:(1)粒度非常规则,生产时性能可控制。(2)粉末近似球状,且是清晰的晶态结构(0.5μm铜粉的其它性能为:含Cu>99％,比表面约为1.5米~2/克,氧含量约0.3％)。
Last year, West Germany Hamburg North Deutscher Metallurgical Company has been a large number of pilot production of ultrafine copper powder of various sizes from less than 0.5 microns to a maximum of 10 microns. Copper powder using a new chemical technology (registered patent) manufacturing, copper performance are as follows: (1) the particle size is very regular, the performance of production control. (2) The powder is nearly spherical and has a clear crystalline structure (0.5μm copper powder with other properties: Cu> 99%, specific surface area of about 1.5-2 / g and oxygen content of about 0.3%).
