Compounds with metal cations (positively charged ... for understanding the underlying reactions that make ferric chloride good at etching copper. In solution, ferric chloride rapidly dissociates ...

He recently worked out a relatively inexpensive and easy way to etch metals using some chemistry skill and a little bit of electricity. After preparing a set of stencils and cleaning the metal ...

Etching is also used for surface preparation with minimal metal removal (microetching ... The most common etching systems are based on alkaline ammonia and cupric chloride. Other systems include ...
