摘要
A method for producing high density and ultrafine W/Cu bulk material by a mechano-chemical process is disclosed. In the method of this invention, metal salts as start materials are spray-dried and prepare W-- Cu precursor powder having uniformly-dispersed tungsten and copper components. The W--Cu precursor powder in turn is subjected to a desalting and milling process, thus preparing W--Cu oxide composite powder. Thereafter, the W--Cu oxide composite powder may be formed into a formed green body prior to reducing and sintering under hydrogen atmosphere.
