Alluminium in concentrated nitric acid(>60%) leads to formation of a passive oxide layer which acts as a barrier to any further reaction.
Alluminium in dilute nitric acid is what causes confusion to me.
I was planning on building some apparatus for parting my inquarted gold which will be continuously exposed to boiling nitric acid.
The material I am considering is alluminium or anodised alluminium(oxidised alluminium).
I am unsure how either of the two reacts with dilute nitric acid.
Alluminium oxide is insoluble in water.
Reading online has further added to my confusion.
If there are people who have any experience working with the two, your knowledge would be greatly appreciated.
I would be happy to provide any clarifications.
Thanks.
