metallic container for corrosive chemicals

nikotyna1939 - 13-3-2019 at 01:25

what kind of pure metal or alloys is the best for handling corrosive chemical like elemental halogens and mineral acids in any concentration at room temperature.
also no noble metal please
i need to use metals because is cold conductive

[Edited on 14-3-2019 by nikotyna1939]

halogens like chlorine bromine and iodine
mineral acid like nitric HCL HBR and HI

Nothing is immune to everything so you will have to be more specific.

Off-hand I can't think of available metals that can contain aqua regia for example, but glass is inert to it - Hydrofluoric acid eats glass but not plastic ........

It's unfortunate that Godnuclear fusion didn't make more noble metals for Earth, otherwise they'd have been cheaper:mad:

You've a far too wide a range of materials - some acids can be handled in some grades of stainless steel at certain concentrations, Titanium is a possibility for some acids/concentrations, but nothing metal will handle all the materials you've specified. I'm not sure why the container has to be metal (for structural purposes?) and if you need that then perhaps look at glass coated steel vessels or plastic coated steel vessels, but again no one coating will work for the complete range of materials you've specified.

A rhodium (or rhodium plated) container might hold almost all acids but will probably get destroyed with the halogens.

PTFE can hold up to almost everything but it is obviously not a metal.

Please be more specific.

Teflon coated steel or aluminium is the only thing that stands up to all these but you would need a airtight lid to store that type of stuff.plastic sounds like a better idea.

A crystaline carbon RBF should fulfill all of the requirements mentioned - at STP.

Crystaline carbon sounds like diamond.
