Colors of tantalum oxide coatings

Dear readers,

I am looking for color charts of anodized tantalum: the colors of the oxide films scale vary nicely with applied voltage (and are beautiful!) and I would like to determine the thickness by comparison to color vs. oxide thickness charts (for a lab class). I know these charts exist but haven't been able to find them. If anybody knows where they are, please let me know,

P.S. Thanks very much for the replies to my previous question; they were very helpful.

Hi, Gerko. Sorry that your question is unanswered. But letter 33261 suggests that the colors are similar to titanium, and the author of that claim can probably help you with some details. Good luck with it!

Regards,

Ted Mooney, P.E.
