Tantalum Testing- standards
(OP)
I am having trouble obtaining reference materials containing tantalum with certified values. I am working on setting-up calibration curves on an optical emission spectrometer to test PH 17-4 materials.
Does anyone know where I could obtain CRM's with certified Ta values for this purpose?

It has been my experience that your are lucky just to get repeatable analyses of 17/4. Ta is bear to analyze in a stainless matrix. We had a lot of components “Tantalated” and tried very hard do analytical work on the materials with very little success.

So check out AMS 5643 for 17-4 bar, for instance, and you'll see that Ta is no longer required to be analyzed. If you buy to ASTM specifications, perhaps an e-mail to the proper committee would cause them to review the situation.
Good luck!
