Acetic & Mixed Acids

Hey Guys,

I have no experience with tantalum but heard its extremely corrosion resistant and might work in my application so I am looking for some advice.

My application is primarily acetic acid with a variety of other acids mixed in at much lower concentrations. How concerned do I need to be about the minor acid components?

Hello Kent,

Without knowing the exact concentrations and temperatures I could only talk generally about tantalum and its corrosion resistance to acetic acid. However in most conditions used by industry in the production of acetic acid tantalum could be used and could easily substitute for zirconium metal.

Generally speaking because tantalum metal is so inert and does not react with the various media the minor components of your acid solution should not be problem unless it was mixed with HF. HF is one of the few acids that will readily attack tantalum metal.
