H2O2 resistance

thread338-68378

H2O2 resistance

H2O2 resistance

(OP)
Can anyone provide me with info on materials with resistance to attack by concentrated (e. g., >80%) hydrogen peroxide (H2O2)?

How do the following materials in particular hold up:

Ni, Mo, graphite, boron nitride, SiC, TiB2?

RE: H2O2 resistance

graphite is a question mark. at that concentration a lot of carbon materials actually catalyze decomposition. Molly could be a problem. seems that in its pure form the oxidatized surface does not remain intact.

you also have to worry abit about the inhibitor used to stabilize the solution.

s.s. is the usual material of construction.

RE: H2O2 resistance

What kind of equipment are you looking for?  The kind of equipment required could help in determing the right materials of construction.  i.e. are elastomeric seals required? Is the equipment even rotating or is it static, like a storage tank, etc.  Is it short term exposure or long term?

Also, what is the temperature?

I want to use ceramic in a 90% H2O2 environment. I want to know what will hold up and what not.
