chemical resistance of materials
(OP)
Hi all,
I am loocking for some informations about the chemical resistance of acetal resin (Delrin), copper and titanium parts in LiOH, NH4OH, GdNO3 environments.
Thank you!

Hope that helps.

Also, consult with your suppliers of Delin and the alloys for their recommendation of compatibility, AND with the manufacturers/suppliers of the reagents that you list. If you are buying GdNO3 from a company, they have to be keeping it in something, right?

Gd(NO3)3 + 3H2O -> Gd(OH)3 + 3HNO3
From this, we could say that the suspected reactive agent in water would be nitric acid. According to the chemical resistance charts provided by Cole Parmer (www.ColeParmer.com), titanium will be fine in nitric acid up to 72ºF (22ºC). However, copper and Delrin are not recommended.
I hope I will not get flamed too much for my back-of-the-envelope approach here.
