Q. I am the Q.C. and Environmental Manager for a small anodizing and plating job shop. Years ago we went away from chromated de-oxidizers and have been using an iron based deoxider ever since. Sometimes we even mix it up ourselves using raw chemicals instead of a proprietary product. I read an article recently that mentioned sodium bromate as a deoxidizer for aluminum but it did not elaborate on concentration or any other ingredients. Does anyone have a recipe that we might try?

? Would you give us the reference for that article, name, publication, issue?
Thanks,

If I'm not mistaken (I seem to have misplaced the issue) the bromate deoxidizer was referred to in the December 2001 issue of Metal Finishing in the article "An Overview of Non-hexavalent Chromium Conversion Coatings - Part 1, Aluminum & Its Alloys"

? Did not see article but was the use of peroxy oxidizers suggested?

A. I own a small metal finishing chemical manufacturing company and we make a bromate deox. It's our own formula, and I don't know how the inventor came up with it because he won't tell me. Probably ripped off from the US military in the 80's.
