Hi,
We are working with moly furnace components at the moment. We were under
the assumption that moly was unaffected by strong acids, yet, when we
immersed our pure moly sample in fuming nitric acid, it rapidly
developed a loose dark red deposit. Given that we are immersing the
components in 1600 deg C Calcium fluoride, we want to avoid nasty
suprises, like the moly is impure in some way.
I would be very grateful for any comments on just what we have seen. Is
it a moly oxide of some kind ? Moly Trioxide of course is clear/white.
Thanks for any help.
