The phosphating mechanism of copper powders also suggested that insoluble phosphates are deposited on the surface of copper particles and that the surface corrosion of copper powders is carried out by NO−3under acidic conditions.
Despite the distinct roles of these proteins in copper trafficking, all seem able to respond to changes in copper status.
These results are similar to those in copper electrodeposits obtained from acid copper sulfate and acid copper fluoborate baths.
The results revealed two copper groups that could be qualified as “dirty” copper and “clean” copper.
The results provide supporting evidence for proposed reactions of copper with H + hfac which are thought to be responsible for the vapor-phase etching of copper.
Results are partially in contrast with the few experimental data available in the technical literature, that are by the way about high purity UFG copper.
